1 This is a list of the status of GNU Emacs on various machines and systems.
3 For each system and machine, we give the configuration name you should
4 pass to the `configure' script to prepare to build Emacs for that
7 The `configure' script uses the configuration name to decide which
8 machine and operating system description files `src/config.h' should
9 include. The machine description files are all in `src/m', and have
10 names similar to, but not identical to, the machine names used in
11 configuration names. The operating system files are all in `src/s',
12 and are named similarly. See the `configure' script if you need to
13 know which configuration names use which machine and operating system
16 If you add support for a new configuration, add a section to this
17 file, and then edit the `configure' script to tell it which
18 configuration name(s) should select your new machine description and
19 system description files.
22 Here are the configurations Emacs is intended to work with, with the
23 corresponding configuration names. You can postpend version numbers
24 to operating system names (i.e. sunos4.1) or architecture names (i.e.
25 hppa1.1). If you leave out the version number, the `configure' script
26 will configure Emacs for the latest version it knows about.

36 *************************************************************************
38 Acorn RISCiX (arm-acorn-riscix1.2)
40 Emacs 19.29 has changes that ought to support RISCiX 1.2.
42 Due to a bug in the RISCiX C compiler (3.4.5), emacs must
43 be built with gcc (versions 2.5.8 onwards).
45 In addition, you will need GNU sed and GNU make, as the RISCiX release
46 versions of these utilities cannot cope with building emacs-19!
48 GNU sed should be configured with:
50 env 'DEFS=-Dgetopt=gnu_getopt -Dopterr=gnu_opterr -Doptind=gnu_optind \
51 -Doptarg=gnu_optarg' ./configure
53 GNU make (3.72+) should be configured with:
55 env 'CFLAGS=-Dgetopt=gnu_getopt -Dopterr=gnu_opterr -Doptind=gnu_optind \
56 -Doptarg=gnu_optarg' ./configure
58 Emacs may be configured to use the X toolkit, by adding --with-x-toolkit
59 to the configure command. If you do this, you will need to edit the line
60 in src/Makefile which defines LIBW (about line 59) to read:
64 This ensures that the non-shared widget library is used.
66 It is unlikely that this version of emacs will work with RISCiX 1.1.
68 Alliant (fx80-alliant-bsd):
70 18.52 worked on system version 4. Previous Emacs versions were
71 known to work on previous system versions.
73 If you are using older versions of their operating system, you may
74 need to edit `src/config.h' to use `m/alliant1.h' (on version 1) or
75 `m/alliant.h' (on versions 2 and 3).
77 Alliant FX/2800 (i860-alliant-bsd)
79 Known to work with 19.26 and OS version 2.2, compiler version 1.3.
81 Alpha (DEC) running OSF/1 (alpha-dec-osf1)
83 Worked as of Lucid Emacs 19.8.
85 Altos 3068 (m68k-altos-sysv)
87 18.52 was said to work, provided you don't compile unexec.c with -O.
89 Amdahl UTS (580-amdahl-sysv)
91 Small changes for 18.38 were merged in 18.39. It is mostly
92 working, but at last report a bug sometimes causes Emacs to
93 grab very large amounts of memory. No fix or explanation
94 has yet been reported. It may be possible to find this bug
95 if you find which Emacs command it happens within and then
96 run that command with a breakpoint set at malloc.
98 The 5.2u370 compiler is so brain damaged that it is not
99 even worth trying to use it. Success was obtained with the
100 uts native C compiler on uts version 5.2.5.
102 Apollo running Domain (m68k-apollo-domain)
104 19.29 has a few patches that ought to make things work.
106 There are reports of bugs in cc -O on this system.
108 In `lib-src/Makefile', don't expect emacsclient and emacsserver to
109 compile. You might want to remove them from your makefile.
111 The Apollo has a bizarre operating system which does not permit
112 Emacs to be dumped with preloaded pure Lisp code. Therefore, each
113 time you start Emacs on this system, the standard Lisp code is loaded
114 into it. Expect it to take a long time. You can prevent loading of
115 the standard Lisp code by specifying the -nl switch. It must
116 come at the beginning of the command line; only the -t and -batch
117 switches may come before it.
120 Here is a design for a method of dumping and reloading the relevant
121 necessary impure areas of Emacs.
123 On dumping, you need to dump only the array `pure' plus the
124 locations that contain values of forwarded Lisp variables or that are
125 protected for garbage collection. The former can be found by a
126 garbage- collection-like technique, and the latter are in the
127 staticprolist vector (see alloc.c for both things).
129 Reloading would work in an Emacs that has just been started; except
130 when a switch is specified to inhibit this, it would read the dump
131 file and set all the appropriate locations. The data loaded must be
132 relocated, but that's not hard. Those locations that are of type
133 Lisp_Object can be found by a technique like garbage-collection, and
134 those of them that point to storage can be relocated. The other data
135 read from the file will not need to be relocated.
137 The switch to inhibit loading the data base would be used when it
138 is time to dump a new data base.
140 This would take a few seconds, which is much faster than loading
141 the Lisp code of Emacs from scratch.
143 AT&T 3b2, 3b5, 3b15, 3b20 (we32k-att-sysv)
145 Emacs will probably not work with certain kernel constants too small.
147 In param.h CDLIMIT should be at least (1L << 12) in order to allow
148 processes to write up to 2 Mbyte files. This parameter is configurable
149 by normal means in /etc/master.d/kernel; examine that file for the
150 symbol CDLIMIT or ULIMIT, and raise it by several powers of 2. Then
151 do normal kernel rebuild things via "cd /boot; mkboot -k KERNEL" and so
154 In seg.h NSEGP and STACKSEG should be at least 16 and 4 respectively
155 to allow processes with total size of up to 2Mbytes.
156 However, I'm told it is unlikely this would fail to be true.
158 The MAXMEM may also prevent Emacs from running. The file
159 3B-MAXMEM in this directory explains how to increase MAXMEM.
161 On some of these machines, you may need to define IN_SCCS_ID
162 in config.h to make Emacs work. Supposedly you can tell whether
163 this is necessary by checking something in /usr/include/sys/time.h;
164 we do not know precisely what.
166 AT&T 7300 or 3b1 (m68k-att-sysv)
168 18.52 worked. If you have strange troubles with dumping
169 Emacs, delete the last few lines from `src/m/7300.h' and recompile.
170 These lines are supposed to produce a sharable executable.
172 `src/m/7300.h' defines SHORTNAMES because operating system versions
173 older than 3.5 did not support long symbol names. Version 3.5 does
174 support them, so you can remove the #define SHORTNAMES in that
177 Bull DPX/2 models 2nn or 3nn (m68k-bull-sysv3)
179 Minor fixes merged into 19.19, which should work with CC or GCC.
181 You should compile with all the POSIX stuff: undef _SYSV and define
182 _POSIX_SOURCE, _XOPEN_SOURCE and _BULL_SOURCE.
184 On bos2.00.45 there is a bug that makes the F_SETOWN fcntl
185 call enters in an infinite loop. F_SETOWN_BUG has been defined to avoid
188 Bull DPX/20 (rs6000-bull-bosx)
192 Bull sps7 (m68k-bull-sysv2)
194 Changes partially merged in version 19, but some fixes are probably required.
200 Celerity (celerity-celerity-bsd4.2)
202 Version 18.49 worked. This configuration name is a hack, because we
203 don't know the processor used by Celerities. If someone
204 who uses a Celerity could get in touch with us, we can teach
205 config.sub a better name for the configuration.
207 Clipper (clipper-???)
209 Version 19 has support for some brand of clipper system. If you
210 have successfully built Emacs 19 on some sort of clipper system, let
211 us know so we can flesh out this entry.
213 Note that the Orion 105 is also a clipper, but some system-related
214 parameters are different.
216 Convex (c1-convex-bsd, c2-convex-bsd, c32-convex-bsd, c34-convex-bsd,
219 Support updated and residual bugs fixed in 19.26.
221 Cubix QBx/386 (i386-cubix-sysv)
223 Changes merged in 19.1. Systems before 2/A/0 may fail to compile etags.c
224 due to a compiler bug.
226 Cydra 5 (cydra-cydrome-sysv)
228 18.51 worked in one version of their operating system but stopped
229 working in a newer version. This has not been fixed.
231 Data General Aviion (m88k-dg-dgux)
233 19.23 works; however, the GCC provided with DGUX 5.4R3.00 fails to
234 compile src/emacs.c. GCC 2.5.8 does work.
235 The 19.26 pretest was reported to work; no word on which compiler.
237 System versions other than DGUX 5.4R3.00 have not been tested.
239 DECstation (mips-dec-ultrix or mips-dec-osf)
241 This machine is the older Mips-based DECstation.
242 Emacs should now work on the Alpha CPU.
244 19.25 works on Ultrix 4.2. The 19.26 pretest was reported to work
245 on Ultrix 4.2a and on 4.4.
247 One user reported 19.25 did not work at all with --with-x-toolkit
248 using X11R5 patch level 10, but worked ok with X11R5 pl26.
250 See under Ultrix for problems using X windows on Ultrix.
251 Note that this is a MIPS machine.
253 For Ultrix versions 4.1 or earlier, you may need to define
254 SYSTEM_MALLOC in `src/m/pmax.h', because XvmsAlloc.o in libX11.a seems
255 to insist on defining malloc itself.
257 For Ultrix versions prior to 4.0, you may need to delete
258 the definition of START_FILES from `src/m/pmax.h'.
260 Motorola Delta 147 (m68k-motorola-sysv)
262 The EMacs 19.26 pretest was reported to work.
264 Motorola Delta boxes running System V/68 release 3.
265 Tested on 147 board with SVR3V7, no X and gcc.
266 Tested on 167 board with SVR3V7, no X, cc, gnucc and gcc.
267 Reports say it works with X too.
269 The installation script chooses the compiler itself. gnucc is
272 Motorola Delta 187 (m88k-motorola-sysv,
273 m88k-motorola-sysvr4, or
274 m88k-motorola-m88kbcs)
276 The 19.26 pretest was reported to run on SVR3. However, if you
277 use --with-x-toolkit on svr3, you will have problems compiling some
278 files because time.h and sys/time.h get included twice.
279 One fix is to edit those files to protect against multiple inclusion.
281 As of version 19.13, Emacs was reported to run under SYSVr3 and SYSVr4.
283 Dual running System V (m68k-dual-sysv)
285 As of 17.46, this worked except for a few changes
288 Dual running Uniplus (m68k-dual-uniplus)
292 Elxsi 6400 (elxsi-elxsi-sysv)
294 Changes for 12.0 release are in 19.1.
295 Dumping should work now.
297 Encore machine (ns16k-encore-bsd)
299 This machine bizarrely uses 4.2BSD modified to use the COFF format
300 for object files. Works (as of 18.40). For the APC processor you
301 must enable two lines at the end of `src/s/umax.h', which are commented
302 out in the file as distributed.
304 WARNING: If you compile Emacs with the "-O" compiler switch, you
305 must also use the "-q enter_exits" switch so that all functions have
306 stack frames. Otherwise routines that call `alloca' all lose.
308 A kernel bug in some system versions causes input characters to be lost
311 GEC 63 (local-gec63-usg5.2)
313 Changes are partially merged in version 18, but certainly require
314 more work. Let us know if you get this working, and we'll give it a
315 real configuration name.
317 Gould Power Node (pn-gould-bsd4.2 or pn-gould-bsd4.3)
319 18.36 worked on versions 1.2 and 2.0 of the operating system.
321 On UTX/32 2.0, use pn-gould-bsd4.3.
323 On UTX/32 1.2 and UTX/32S 1.0, use pn-gould-bsd4.2 and note that
324 compiling `lib-src/sorted-doc' tickles a compiler bug: remove the -g
325 flag to cc in the makefile.
327 UTX/32 1.3 has a bug in the bcopy library routine. Fix it by
328 #undef BSTRING in `src/m/gould.h'.
330 Version 19 incorporates support for releases 2.1 and later of UTX/32.
331 A site running a pre-release of 2.1 should #define RELEASE2_1 in config.h.
333 Gould NP1 (np1-gould-bsd)
335 Version 19 supposedly works.
337 Harris Night Hawk (m68k-harris-cxux or m88k-harris-cxux)
339 This port was added in 19.23. The configuration actually tested was
340 a Night Hawk 4800 running CX/UX 7.0.
342 If you have GCC ported and want to build with it, you probably need to
343 change things (like compiler switches) defined in the s/cxux.h file.
345 With CX/UX 7.0 and later releases, you need to build after setting the
346 SDE_TARGET environment variable to COFF (a port using ELF and shared
347 libraries has not yet been done).
349 Honeywell XPS100 (xps100-honeywell-sysv)
351 Config file added in version 19.
353 Hewlett-Packard 9000 series 200 or 300 (m68k-hp-bsd or m68k-hp-hpux7.)
355 Version 19 works under BSD. The 19.26 pretest was reported
358 These machines are 68000-series CPUs running HP/UX
359 (a derivative of sysV with some BSD features) or BSD 4.3 ported by Utah.
360 The operating system suffix determines which system Emacs is built for.
362 Series 200 HPUX runs Emacs only if it has the "HP/UX upgrade".
364 If you are running HP/UX release 8.0 or later, you need the optional
365 "C/ANSI C" software in order to build Emacs (older releases of HP/UX
366 do not require any special software). If the file "/etc/filesets/C"
367 exists on your machine, you have this software, otherwise you do not.
369 Note that HP has used two incompatible assembler syntaxes,
370 and has recently changed the format of C function frames.
371 `src/crt0.c' and `src/alloca.s' have been conditionalised for the new
372 assembler and new function-entry sequence. You may need to define
373 OLD_HP_ASSEMBLER if you are using an older hpux version. If you
374 have an official (bought from HP) series 300 machine you have
375 the new assembler. Kernels that are 5.+ or later have new
376 assembler. A Series 200 that has been upgraded to a 68010
377 processor and a 5.+ kernel has the new compiler.
379 Define C_SWITCH_MACHINE to be +X to make a version of Emacs that
380 runs on both 68010 and 68020 based HP/UX's.
382 Define HPUX_68010 if you are using the new assembler, for
383 a system that has a 68010 without a 68881. This is to say,
384 a s200 (upgraded) or s310.
386 Define the symbol HPUX_NET if you have the optional network features
387 that include the `netunam' system call. This is referred to as
388 Network Services (NS/9000) in HP literature.
390 HP 9000 series 500: not supported.
392 The series 500 has a seriously incompatible memory architecture
393 which relocates data in memory during execution of a program,
394 and support for it would be difficult to implement.
396 HP 9000 series 700 or 800 (Spectrum) (hppa1.0-hp-hpux or hppa1.1-hp-hpux
399 19.26 is believed to work on HPUX 9 provided you compile with GCC.
400 As of version 19.16, Emacs was reported to build (using GCC) and run
401 on HP 9000/700 series machines running HP/UX versions 8.07 and 9.01.
403 Use hppa1.1 for the 700 series and hppa1.0 for the 800
404 series machines. (Emacs may not actually care which one you use.)
406 Use hppa1.1-hp-hpux9shr to use shared libraries on HPUX version 9.
407 You may need to create the X libraries libXaw.a and libXmu.a from
408 the MIT X distribute, and you may need to edit src/Makefile's
409 definition of LIBXT to look like this:
411 LIBXT= $(LIBW) -lXmu -lXt $(LIBXTR6) -lXext
413 Some people report trouble using the GNU memory allocator under
414 HP/UX version 9. The problems often manifest as lots of ^@'s in the
417 We are told that these problems go away if you obtain the latest
418 patches for the HP/UX C compiler. James J Dempsey
419 <jjd@spserv.bbn.com> says that this set of versions works for him:
421 HP92453-01 A.09.28 HP C Compiler
423 HP92453-01 A.09.28 HP C Compiler
424 HP-UX SLLIC/OPTIMIZER HP-UX.09.00.23 02/18/93
425 Ucode Code Generator - HP-UX.09.00.23.5 (patch) 2/18/93
427 For 700 series machines, the HP-UX patch needed is known as
428 PHSS_2653. (Perhaps for 800 series machines as well; we don't
429 know.) If you are on the Internet, you should be able to obtain
430 this patch by using telnet to access the machine
431 support.mayfield.hp.com and logging in as "hpslreg" and following
432 the instructions there. Do not ask FSF for further support on
433 this. If you have any trouble obtaining the patch, contact HP
436 If your buffer fills up with nulls (^@) at some point, it could well
437 be that problem. That problem does not happen when people use GCC
438 to compile Emacs. On the other hand, the HP compiler version 9.34
439 was reported to work for the 19.26 pretest. 9.65 was also reported to work.
441 If you turn on the DSUSP character (delayed suspend),
442 Emacs 19.26 does not know how to turn it off on HPUX.
443 You need to turn it off manually.
445 If you are running HP/UX release 8.0 or later, you need the optional
446 "C/ANSI C" software in order to build Emacs (older releases of HP/UX
447 do not require any special software). If the file "/etc/filesets/C"
448 exists on your machine, you have this software, otherwise you do not.
450 High Level Hardware Orion (orion-highlevel-bsd)
452 This is the original microprogrammed hardware.
453 Machine description file ought to work.
455 High Level Hardware Orion 1/05 (clipper-highlevel-bsd)
457 Changes merged in 18.52. This is the one with the Clipper cpu.
458 Note that systems which lack NFS need LOAD_AVE_TYPE changed to `double'.
460 C compiler has a bug; it loops compiling eval.c.
461 Compile it by hand without optimization.
463 IBM PS/2 (i386-ibm-aix1.1 or i386-ibm-aix1.2)
465 Changes merged in version 19. You may need to copy
466 /usr/lib/samples/hft/hftctl.c to the Emacs src directory.
468 i386-ibm-aix1.1 may not work with certain new X window managers, and
471 IBM RS/6000 (rs6000-ibm-aix)
473 Emacs 19.26 is believed to work; its pretest was tested.
475 At last report, Emacs didn't run well on terminals. Informed
476 persons say that the tty VMIN and VTIME settings have been
477 corrupted; if you have a fix, please send it to us.
479 Compiling with -O using the IBM compiler has been known
480 to make Emacs work incorrectly. It's reported that on
481 AIX 3.2.5 with an IBM compiler earlier than 1.03.00.14,
482 cc -O fails for some files. You need to install any
483 PTF containing APAR #IX42810 to bring the compiler to
484 the 1.03.00.14 level to allow optimized compiles.
485 Alternatively, recompiling just emacs.c and extents.c
486 without optimization seems to do the trick as well.
488 There are reports that IBM compiler versions earlier than 1.03.00.02
489 fail even without -O.
491 As of 19.11, if you strip the Emacs executable, it ceases to work.
493 If you are using AIX 3.2.3, you may get a core dump when loading
494 ange-ftp. You may be able to fix the problem by defining LIBS_TERMCAP
495 as -ltermcap -lcurses. Please tell us if this fails to work.
497 If anyone can fix the above problems, or confirm that they don't happen
498 with certain versions of various programs, we would appreciate it.
500 IBM RT/PC (romp-ibm-bsd or romp-ibm-aix)
502 Use romp-ibm-bsd for the 4.2-like system and romp-ibm-aix for AIX.
503 19.22 is reported to work under bsd. We don't know about AIX.
505 On BSD, if you have trouble, try compiling with a different compiler.
507 On AIX, the file /usr/lib/samples/hft/hftctl.c must be compiled into
508 hftctl.o, with this result left in the src directory (hftctl.c is
509 part of the standard AIX distribution).
511 window.c must not be compiled with -O on AIX.
513 Integrated Solutions `Optimum V' (m68k-isi-bsd4.2 or -bsd4.3)
515 18.52 said to work on some sort of ISI machine.
516 Version 18.45 worked (running on a Optimum V (VME bus, 68020)
517 BSD 4.2 (3.05e) system). 18.42 is reported to work on
518 a Qbus 68010 system. Has not been tried on `WorkStation' `Cluster
519 Compute Node' `Cluster WorkStation' or `Server Node' (Love the
522 Compilation with -O is rumored to break something.
524 On recent system versions, you may need to undefine the macro UMAX
525 in `lib-src/loadst.c' and `src/getpagesize.h'. They stupidly defined this
526 in a system header file, which confuses Emacs (which thinks that UMAX
527 indicates the Umax operating system).
529 Intel 386 (i386-*-isc, i386-*-esix,
530 i386-*-xenix, i386-*-linux, i386-*-freebsd,
531 i386-intsys-sysv, i386-*-sysv3,
532 i386-*-sysv4, i386-*-sysv4.2,

535 or i486... or i586...)
537 In the above configurations, * means that the manufacturer's name
538 you specify does not matter, and you can use any name you like
539 (but it should not contain any dashes or stars).
541 When using the ISC configurations, be sure to specify the isc
542 version number - for example, if you're running ISC 3.0, use
543 i386-unknown-isc3.0 as your configuration name.
544 Use i386-*-esix for Esix; Emacs runs as of version 19.6.
545 Use i386-*-linux for GNU/Linux systems; Emacs runs as of version 19.26.
546 Use i386-intsys-sysv for Integrated Solutions 386 machines.
547 It may also be correct for Microport systems.
548 Use i386-*-sco3.2v4 for SCO 3.2v4; Emacs runs as of version 19.26.
550 On GNU/Linux systems, Emacs 19.23 was said to work properly with libc
551 version 4.5.21, but not with 4.5.19. If your system uses QMAGIC
552 for the executable format, you must edit config.h to define LINUX_QMAGIC.
554 On GNU/Linux, configure may fail to put these definitions in config.h:
556 #define HAVE_GETTIMEOFDAY
560 To work around the problem, add those definitions by hand.
561 It is possible that this problem happens only with X11R6
562 or that newer system versions have fixed it.
564 The 19.26 pretest was reported to work on SVR4.3 and on Freebsd.
566 Use i386-*-bsd386 for BSDI BSD/386; Emacs runs as of version 19.23.
567 Make on that system is broken; use GNU make instead.
568 Shell bugs in version 1.0 of BSD/386 cause configure
569 to do the wrong thing with --with-x-toolkit; the workaround is to edit
570 configure to run another shell such as bash.
572 For System V release 3, use i386-*-sysv3.
573 For System V release 4, use i386-*-sysv4.
574 For System V release 4.2, use i386-*-sysv4.2.
576 If you are using Xenix, see notes at end under Xenix.
577 If you are using Esix, see notes at end under Esix.
578 If you are using SCO Unix, see notes at end under SCO.
580 On 386bsd, netbsd and freebsd, you should use GNU make, not the
581 system's make. Assuming it's installed as gmake, do `gmake install
584 If you are using System V release 4.2, you may find that `cc -E'
585 puts spurious spaces in `src/xmakefile'. If that happens,
586 specify CPP=/lib/cpp as an option when you run make.
587 There is no problem if you compile with GCC.
589 Note that use of Linux with GCC 2.4 and the DLL 4.4 libraries
590 requires the experimental "net 2" network patches (no relation to
591 Berkeley Net 2). There is a report that (some version of) Linux
592 requires including `/usr/src/linux/include/linux' in buffer.c
593 but no coherent explanation of why that might be so. If it is so,
594 in current versions of Linux, something else should probably be changed.
596 Some sysV.3 systems seem to have bugs in `opendir';
597 for them, alter `config.h' to define NONSYSTEM_DIR_LIBRARY
598 and undefine SYSV_SYSTEM_DIR.
600 If you use optimization on V.3, you may need the option -W2,'-y 0'
601 to prevent certain faulty optimization.
603 On 386/ix, to link with shared libraries, add #define USG_SHARED_LIBRARIES
606 On SCO, there are problems in regexp matching when Emacs is compiled
607 with the system compiler. The compiler version is "Microsoft C
608 version 6", SCO 4.2.0h Dev Sys Maintenance Supplement 01/06/93;
609 Quick C Compiler Version 1.00.46 (Beta). The solution is to compile
612 On ISC systems (2.02 and more recent), don't try to use the versions
613 of X that come with the system; use XFree86 instead.
615 There is no consistency in the handling of certain system header files
618 Some versions have sys/sioctl.h, and require it in sysdep.c.
619 But some versions do not have sys/sioctl.h.
620 For a given version of the system, this may depend on whether you have
621 X Windows or TCP/IP. Define or undefine NO_SIOCTL_H in config.h
622 according to whether you have the file.
624 Likewise, some versions have been known to need sys/ttold.h, sys/stream.h,
625 and sys/ptem.h included in sysdep.c. If your system has these files,
626 try defining NEED_PTEM_H in config.h if you have trouble without it.
628 You may find that adding -I/usr/X/include or -I/usr/netinclude or both
629 to CFLAGS avoids compilation errors on certain systems.
631 Some versions convince sysdep.c to try to use `struct tchars'
632 but define `struct tc' instead; add `#define tchars tc'
633 to config.h to solve this problem.
635 Iris 2500 and Iris 2500 Turbo (m68k-sgi-iris3.5 or m68k-sgi-iris3.6)
637 Version 18 was said to work; use m68k-sgi-iris3.5 for system version 2.5
638 and m68k-sgi-iris3.6 for system version 3.6.
639 Note that the 3030 is the same as the Iris 2500 Turbo.
641 Iris 4D (mips-sgi-irix[456].*)
643 The 19.26 pretest was reported to work on IRIX 4.0.5 and 5.2.
644 19.23 was reported to work on IRIX 5.2, but you may need to install
645 the "compiler_dev.hdr.internal" subsystem in order to compile unexelfsgi.c.
646 19.22 was known to work on all Silicon Graphics machines running
647 IRIX 4.0.5 or IRIX 5.1.
649 Compiling with -O using IRIX compilers prior to 3.10.1 may not work.
650 Don't use -O or use GCC instead.
652 Most IRIX 3.3 systems do not have an ANSI C compiler, but a few do.
653 Compile Emacs 18 with the -cckr switch on these machines.
655 There is a bug in IRIX 3.3 that can sometimes leave ptys owned by root
656 with a permission of 622. This causes malfunctions in use of
657 subprocesses of Emacs. Irix versions 4.0 and later with GNU Emacs
658 versions 18.59 and later fix this bug.
660 Masscomp (m68k-masscomp-rtu)
662 18.36 worked on a 5500DP running RTU v3.1a and compiler version 3.2
663 with minor fixes that are included in 18.37. However, bizarre behavior
664 was reported for 18.36 on a Masscomp (model and version unknown but probably
665 a 68020 system). The report sounds like a compiler bug.
667 A compiler bug affecting statements like
668 unsigned char k; unsigned char *p;... x = p[k];
669 has been reported for "C version 1.2 under RTU 3.1". We do not wish
670 to take the time to install the numerous workarounds required to
671 compensate for this bug.
673 For RTU version 3.1, define FIRST_PTY_LETTER to be 'p' in `src/s/rtu.h'
674 (or #undef and redefine it in config.h) so that ptys will be used.
676 GNU Emacs is said to have no chance of compiling on RTU versions
679 Megatest (m68k-megatest-bsd)
681 Emacs 15 worked; do not have any reports about Emacs 16 or 17
682 but any new bugs are probably not difficult.
684 Mips (mips-mips-riscos, mips-mips-riscos4.0, or mips-mips-bsd)
686 The C compiler on Riscos 4.51 dumps core trying to optimize
687 parts of Emacs. Try without optimization or try GCC.
689 Meanwhile, the linker on that system returns success even if
690 there are undefined symbols; as a result, configure gets the
691 wrong answers to various questions. No work-around is known
692 except to edit src/config.h by hand to indicate which functions
695 Use mips-mips-riscos4.0 for RISCOS version 4.
696 Use mips-mips-bsd with the BSD world.
698 Note that the proper configuration names for DECstations are
699 mips-dec-ultrix and mips-dec-osf.
701 If you are compiling with GCC, then you must run fixincludes;
702 the alternative of using -traditional won't work because
703 the definition of SIGN_EXTEND_CHAR uses the keyword `signed'.
705 If the SYSV world is the default, then you probably need the following
706 line in etc/Makefile:
708 CFLAGS= -g -systype bsd43
710 Some operating systems on MIPS machines give SIGTRAP for division by
711 zero instead of the usual signals. The only real solution is to fix
712 the system to give a proper signal.
714 In the meantime, you can change init_data in data.c if you wish.
715 Change it to handle SIGTRAP as well as SIGFPE. But this will have a
716 great disadvantage: you will not be able to run Emacs under a
717 debugger. I think crashing on division by zero is a lesser problem.
719 dsg@mitre.org reported needing to use --x-libraries=/bsd43/usr/lib
720 on a riscos4bsd site. But it is not clear whether this is needed in
721 general or only because of quirks on a particular site.
723 National Semiconductor 32000 (ns32k-ns-genix)
725 This is for a complete machine from National Semiconductor,
726 running Genix. Changes merged in version 19.
728 NCR Tower 32 (m68k-ncr-sysv2 or m68k-ncr-sysv3)
730 If you are running System V release 2, use m68k-ncr-sysv2.
731 If you are running System V release 3, use m68k-ncr-sysv3.
733 These both worked as of 18.56. If you change `src/ymakefile' so that
734 CFLAGS includes C_OPTIMIZE_SWITCH rather than C_DEBUG_SWITCH, check
735 out the comments in `src/m/tower32.h' (for System V release 2) or
736 `src/m/tower32v3.h' (for System V release 3) about this.
738 There is a report that compilation with -O did not work with 18.54
739 under System V release 2.
741 NCR Intel system (i386-ncr-sysv4.2)
743 This system works in 19.31, but if you don't link it with GNU ld,
744 you may need to set LD_RUN_PATH at link time to specify where
745 to find the X libraries.
747 NeXT (m68k-next-nextstep)
749 Emacs 19 has not been tested extensively yet, but it seems to work
750 in a NeXTStep 3.0 terminal window, and under the X server called
751 co-Xist. You may need to specify -traditional when src/Makefile
754 NeXT users might want to implement direct operation with NeXTStep,
755 but from the point of view of the GNU project, that is a
758 Thanks to Thorsten Ohl for working on the NeXT port of Emacs 19.
760 Nixdorf Targon 31 (m68k-nixdorf-sysv)
762 Machine description file for version 17 is included in 18
763 but whether it works is not known.
764 `src/unexec.c' bombs if compiled with -O.
765 Note that the "Targon 35" is really a Pyramid.
767 Nu (TI or LMI) (m68k-nu-sysv)
769 Version 18 is believed to work.
771 Paragon OSF/1 (i860-intel-osf1)
773 Changes merged in 19.29.
775 There is a bug in OSF/1 make which claims there is a syntax error
776 in the src/xmakefile. You can successfully build emacs with:
780 Plexus (m68k-plexus-sysv)
784 Pmax (DEC Mips) (mips-dec-ultrix or mips-dec-osf1)
786 See under DECstation, above.
788 Prime EXL (i386-prime-sysv)
790 Minor changes merged in 19.1.
792 Pyramid (pyramid-pyramid-bsd)
794 The 19.26 pretest was observed to work on OSx 5.0, but it is necessary
795 to edit gmalloc.c. You must add #include <sys/types.h> at the top,
796 and delete the #define for size_t.
798 You need to build Emacs in the Berkeley universe with
799 the `ucb' command, as in `ucb make' or `ucb build-install'.
801 In OSx 4.0, it seems necessary to add the following two lines
802 to `src/m/pyramid.h':
803 #define _longjmp longjmp
804 #define _setjmp setjmp
806 In Pyramid system 2.5 there has been a compiler bug making
807 Emacs crash just after screen-splitting with Qnil containing 0.
808 A compiler that fixes this is Pyramid customer number 8494,
809 internal number 1923.
811 Some versions of the pyramid compiler get fatal
812 errors when the -gx compiler switch is used; if this
813 happens to you, change `src/m/pyramid.h' to define
814 C_DEBUG_SWITCH with an empty definition.
816 Some old system versions may require you to define PYRAMID_OLD
817 in when alloca.s is preprocessed, in order to define _longjmp and _setjmp.
819 Sequent Balance (ns32k-sequent-bsd4.2 or ns32k-sequent-bsd4.3)
821 Emacs 18.51 worked on system version 3.0. 18.52 is said to work.
822 Delete some lines at the end of `src/m/sequent.h' for earlier system
825 Sequent Symmetry (i386-sequent-bsd, i386-sequent-ptx)
827 Emacs 19 should work on Dynix (BSD). However, if you compile with
828 the Sequent compiler, you may find Emacs does not restore the
829 terminal settings on exit. If this happens, compile with GCC.
831 Emacs 19.27 contains patches that should support
832 DYNIX/ptx 1.4 and 2.1 with the native cc compiler.
834 Gcc can't compile src/process.c due to a non-standard Sequent asm
835 keyword extension supported by cc and used for the network byte/word
836 swapping functions in the PTX /usr/include/netinet/in.h file. Gcc
837 2.5.8 includes the file <sys/byteorder.h> which can be included into
838 netinet/in.h to perform these byte/word swapping functions in the
839 same manner. Patches have been submitted to the FSF against gcc
840 2.6.0 to fix this problem and allow Emacs to be built with gcc.
842 If your machine does not have TCP/IP installed, you will have to edit the
843 src/s/ptx.h file and comment out #define TCPIP_INSTALLED.
845 Siemens Nixdorf RM600 and RM400 (mips-siemens-sysv4)
847 Changes merged in 19.29. This configuration should also work for
848 Pyramid MIS Server running DC-OSX 1.x. The version configured with
849 `--with-x' works without any modifications, but `--with-x-toolkit'
850 works only if the Athena library and the Toolkit library are linked
851 statically. For this, edit `src/Makefile' after the `configure' run
852 and modify the lines with `-lXaw' and `-lXt' as follows:
854 LIBW= /usr/lib/libXaw.a
855 LIBXT= $(LIBW) -lXmu /usr/lib/libXt.a $(LIBXTR6) -lXext
857 SONY News (m68k-sony-bsd4.2 or m68k-sony-bsd4.3)
859 18.52 worked. Use m68k-sony-bsd4.3 for system release 3.
861 SONY News 3000 series (RISC NEWS) (mips-sony-bsd)
863 The 19.26 pretest is reported to work.
865 Some versions of the operating system give SIGTRAP for division by zero
866 instead of the usual signals. This causes division by zero
867 to make Emacs crash. The system should be fixed to give the proper signal.
868 Changing Emacs is not a proper solution, because it would prevent
869 Emacs from working under any debugger. But you can change init_data
870 in data.c if you wish.
872 Stardent i860 (i860-stardent-sysv4.0)
874 19.26 pretest reported to work.
876 Stardent 1500 or 3000
880 Stride (m68k-stride-sysv)
882 Works (most recent news for 18.30) on their release 2.0.
883 For release 2.2, see the end of `src/m/stride.h'.
884 It may be possible to run on their V.1 system but changes
885 in the s- file would be needed.
887 Sun 3, Sun 4 (sparc), Sun 386 (m68k-sun-sunos, sparc-sun-sunos, i386-sun-sunos,
888 sparc-sun-sunos4shr, sparc-sun-solaris2.*,
891 19.26 is believed to work on Sparcs and Sun 3's. Some people report
892 that Emacs crashes immediately on startup when used with a non-X
893 terminal, but we think this is due to compiling with GCC and failing
894 to use GCC's "fixed" system header files.
896 Some Sun versions of X windows use the clipboard, not the selections,
897 for transferring text between clients. The Cut, Paste and Copy items
898 in the menu bar Edit menu work with the clipboard.
900 It's important to include the SunOS version number in the
901 configuration name. For example, for SunOS release 4.0 on a Sun 3,
902 use `m68k-sun-sunos4.0'; for SunOS release 4.1 on a Sparc, use
903 `sparc-sun-sunos4.1'. For SunOS release 4.1.3 on a Sparc, use
904 `sparc-sun-sunos4.1.3'. Use sunos4shr to link with shared libraries
907 (FSF MACHINES file says use of shared libraries does not work with
908 X11R5 or X11R6 on Sunos 4 as of 19.26, but I think this does not
911 Use `m68k' for the 68000-based Sun boxes, `sparc' for Sparcstations,
912 and `i386' for Sun Roadrunners. i386 calls for Sunos4.0.
914 Do not define the environment variable 'KEEP_STATE' while running
917 FSF MACHINES file says the following: (may not apply to XEmacs)
919 If you compile with Sun's ANSI compiler acc, you need additional options
920 when linking temacs, such as
921 /usr/lang/SC2.0.1/values-Xt.o -L/usr/lang/SC2.0.1/cg87 -L/usr/lang/SC2.0.1
922 (those should be added just before the libraries) and you need to
923 add -lansi just before -lc. The precise file names depend on the
924 compiler version, so we cannot easily arrange to supply them.
926 On SunOS 4.1.1, do not use /usr/5bin/cc. You can use gcc or/usr/bin/cc.
927 Make sure the environment variable LD_LIBRARY_PATH is not defined.
929 Some people report crashes on SunOS 4.1.3 if SYSTEM_MALLOC is defined.
930 Others have reported that Emacs works if SYSTEM_MALLOC is defined, and not
931 if it is undefined. So far we do not know why results vary in this way.
932 The sources are set up so that SYSTEM_MALLOC is defined; if that crashes,
933 or if you want the benefit of the relocating memory allocator, you can
934 try enabling the #undef SYSTEM_MALLOC in src/s/sunos4-1-3.h.
936 On Solaris 2, you need to install patch 100947-02 to fix a system bug.
937 Presumably this patch comes from Sun. You must alter the definition of
938 LD_SWITCH_SYSTEM if your X11 libraries are not in /usr/openwin/lib.
939 You must make sure that /usr/ucblib is not in your LD_LIBRARY_PATH.
941 On Solaris 2.2, with a multiprocessor SparcCenter 1000, Emacs 19.17 is
942 reported to hang sometimes if it exits while it has one or more
943 subprocesses (e.g. the `wakeup' subprocess used by `display-time').
944 Emacs and its subprocesses become zombies, and in their zombie state
945 slow down their host and disable rlogin and telnet. This is most
946 likely due to a bug in Solaris 2.2's multiprocessor support,
947 rather than an Emacs bug.
949 On Solaris, do not use /usr/ucb/cc. Use /opt/SUNWspro/bin/cc. Make
950 sure that /usr/ccs/bin and /opt/SUNWspro/bin are in your PATH before
951 /usr/ucb. (Most free software packages have the same requirement on
954 If you have trouble using open-network-stream, get the distribution
955 of `bind' (the BSD name-server), build libresolv.a, and link Emacs
956 with -lresolv, by copying the #definition of LIBS_SYSTEM in
957 src/s/sunos4-1.h to src/config.h. This problem is due to obsolete
958 software in the nonshared standard library.
960 If you want to use SunWindows, define HAVE_SUN_WINDOWS
961 in config.h to enable a special interface called `emacstool'.
962 The definition must *precede* the #include "machine.h".
963 System version 3.2 is required for this facility to work.
965 We recommend that you instead use the X window system, which
966 has technical advantages, is an industry standard, and is also
967 free software. The FSF does not support the SunWindows code;
968 we installed it only on the understanding we would not let it
969 divert our efforts from what we think is important.
971 If you are compiling for X windows, and the X window library was
972 compiled to use the 68881, then you must edit config.h according
973 the comments at the end of `src/m/sun3.h'.
975 Note that Emacs on a Sun is not really as big as it looks.
976 As dumped, it includes around 200k of zeros between the
977 original text section and the original data section
978 (now remapped as part of the text). These are never
981 To build a single Emacs that will run on Sun 2 and Sun 3
982 HARDWARE, just build it on the Sun 2.
984 On Sunos 4.1.3, the word is that Emacs can loop infinitely
985 on startup with X due perhaps to a bug in Sunos. Installing all of
986 these Sun patches fixes the problem. We don't know which of them

996 Tadpole 68K (m68k-tadpole-sysv)
998 Changes merged in 19.1.
1000 You may need to edit Makefile to change the variables LIBDIR and
1001 BINDIR from /usr/local to /usr/contrib.
1003 To give movemail access to /usr/mail, you may need to execute
1005 chmod 2755 etc/movemail; chgrp mail etc/movemail
1007 Tahoe (tahoe-tahoe-bsd4.2 or tahoe-tahoe-bsd4.3)
1009 18.52 was known to work on some Tahoes, but a compiler bug intervenes
1010 on others. Some Emacs versions have worked in Unisys 1r4
1011 (not in 1r3) and CCI I.21.
1013 If you have trouble compiling `lib-src/loadst.c', turn off the definition
1014 of DKSTAT_HEADER_FILE in `src/m/tahoe.h'.
1016 Tandem Integrity S2 (mips-tandem-sysv)
1018 Changes merged in 18.56 but subprocess support is turned off.
1019 You will probably want to see if you can make subprocesses work.
1021 You must edit `lib-src/Makefile' to define LOADLIBES = -mld.
1023 Tektronix XD88 (m88k-tektronix-sysv3*)
1025 The 19.26 pretest was reported to work.
1026 Minor changes merged in 19.19.
1028 Tektronix 16000 box (6130?) (ns16k-tektronix-bsd)
1032 Tektronix 4300 (m68k-tektronix-bsd)
1034 Emacs 19.26 pretest reported to work.
1036 Titan P2 or P3 (titan-titan-sysv)
1038 Changes probably merged in version 19.
1040 Ustation E30 (SS5E) (m68k-unisys-unipl)
1042 Changes merged in 18.52; don't know whether they work.
1044 Vaxen running Berkeley Unix (vax-dec-bsd4.1, vax-dec-bsd4.2, vax-dec-bsd4.3),
1045 Ultrix (vax-dec-ultrix),
1046 System V (vax-dec-sysv0, vax-dec-sysv2), or
1051 See under Ultrix for problems using X windows on Ultrix (vax-dec-ultrix).
1053 18.27 worked on System V rel 2 (vax-dec-sysv2).
1055 18.36 worked on System V rel 0 (vax-dec-sysv0).
1057 Richard Levitte <levitte@e.kth.se> distributes a set of patches to
1058 Emacs 18.59 to make it work nicely under VMS. Emacs 19 probably
1059 won't work very well, or even compile. Levitte is working on a
1060 port, so these problems should be fixed in the near future.
1062 Whitechapel MG1 (ns16k-whitechapel-?)
1064 May work. Supposedly no changes were needed except in `src/m/mg1.h'
1065 file. I do not know what Unix version runs on them.
1067 Wicat (m68k-wicat-sysv)
1069 Changes merged as of 18.6; whether they work is unknown.
1070 See comments in `src/m/wicat.h' for things you should change
1071 depending on the system and compiler version you have.
1073 Here are notes about some of the systems supported:
1075 Berkeley 4.1 (bsd4.1)
1079 Berkeley 4.2 (bsd4.2)
1081 Works on several machines.
1083 Berkeley 4.3 (bsd4.3)
1085 Works, on Vaxes at least.
1089 The following was written for Emacs 18.59 and has been
1090 slightly adapted for Emacs 19. It may need more change to be correct.
1092 Use s/usg5-4.h for Esix System V 4.0.[34] systems if you also have
1093 XFree86. If you insist on using the Esix X Window libraries, good
1094 luck. s/esix5r4.h provides a starting point, but doesn't seem to
1095 work consistently. The basic problems involve the need to load
1096 -lX11 *last* in the link command, and even then some things break.
1097 You get best results by installing XFree86 and forgetting about the
1098 Esix stuff unless you want to run IXI xdt3, which really only needs
1099 the Esix X11 shared libraries.
1101 To compile with XFree86, make sure that your LD_LIBRARY_PATH
1102 contains /usr/X386/lib. Be careful if you also have the Esix X
1103 Window libraries that /usr/X386/lib appears *first* in the
1104 LD_LIBRARY_PATH. Then define C_SWITCH_X_SYSTEM -I/usr/X386/include.
1108 See under "Intel 386".
1111 If you have TCP but not X, you need to edit src/s/sco4.h
1112 to define HAVE_SOCKETS.
1114 If you are using MMDF instead of sendmail, you need to remove
1115 /usr/lib/sendmail or modify lisp/paths.el before compiling.
1116 lisp/paths.el (which is loaded during the build) will attempt to use
1117 sendmail if it exists.
1119 If you are using SMAIL, you need to define the macro
1122 System V rel 0 (usg5.0)
1124 Works, on Vaxes and 3bxxx's.
1125 There are some problems in 18.37 due to shortnames/cccp problems:
1126 use the emacs 17 cpp if you have it.
1128 System V rel 2 (usg5.2)
1130 Works on various machines.
1131 On some (maybe all) machines the library -lPW exists and contains
1132 a version of `alloca'. On these machines, to use it, put
1134 #define LIB_STANDARD -lPW -lc
1135 in the `src/m/MACHINENAME.h' file for the machine.
1137 If you find that the character Meta-DEL makes Emacs crash,
1138 find where function init_sys_modes in sysdep.c sets sg.c_cc[VQUIT]
1139 and make it store 7 there. I have as yet no evidence of whether
1140 this problem, known in HP/UX, exists in other system V versions.
1142 System V rel 2.2 (usg5.2.2)
1144 In 5.2.2 AT&T undid, incompatibly, their previous incompatible
1145 change to the way the nlist library is called. A different s- file
1146 is used to enable the other interface.
1148 They call themselves the right choice--can't they choose?
1150 Emacs version 18 unexec is currently not working properly
1151 on 5.2.2. Nobody knows why yet. A workaround is to define
1152 NO_REMAP. It is not yet known whether this applies to all
1153 machines running 5.2.2.
1155 System V rel 3 (usg5.3)
1157 Some versions of this system support ptys and BSD-style sockets.
1158 On such systems, you should define HAVE_PTYS and HAVE_SOCKETS in config.h.
1160 If you want to link Emacs with shared libraries, define
1161 USG_SHARED_LIBRARIES.
1163 You may have to add ANSI idempotence #-lines to your sys/types.h
1164 file to get Emacs to compile correctly. This may be necessary on
1165 other pre-ANSI systems as well.
1167 On an AT&T 6386WGS using System V Release 3.2 and X11R3, the X support
1168 cannot be made to work. Whether or not the GNU relocating malloc is
1169 used, the symptom is that the first call Emacs makes to sbrk(0) returns
1170 (char *)-1. Sorry, you're stuck with character-only mode. Try
1171 installing Xfree86 to fix this.
1173 System V rel 4.0.3 and 4.0.4 (usg5.4)
1175 Supported, including shared libraries for ELF, but ptys do not work
1176 because TIOCGPGRP fails to work on ptys (but Dell 2.2 seems to have
1177 fixed this). This failure is probably due to a misunderstanding of
1178 the consequences of the POSIX spec: many system designers mistakenly
1179 think that POSIX requires this feature to fail. This is untrue;
1180 ptys are an extension, and POSIX says that extensions *when used*
1181 may change the action of standard facilities in any fashion.
1183 If you get compilation errors about wrong number of
1184 arguments to getpgrp, define GETPGRP_NO_ARG.
1186 The standard C preprocessor may generate xmakefile incorrectly. However,
1187 /lib/cpp will work, so use `make CPP=/lib/cpp'. Standard cpp
1188 seems to work OK under Dell 2.2.
1190 Some versions 3 and earlier of V.4, on the Intel 386 and 860, had
1191 problems in the X11 libraries. These prevent Emacs from working
1192 with X. You can use Emacs with X provided your copy of X is based
1193 on X11 release 4 or newer, or is Dell's 2.2 (which is a 4.0.3).
1194 Unfortunately, the only way you can tell whether your X11 library is
1195 new enough is to try compiling Emacs to use X. If emacs runs, your
1196 X11 library is new enough.
1198 In this context, GSV4 and GSV4i are alternate names for X11R4.
1199 OL2.* is X11R3 based. OL3 is in between X11R3 and X11R4, and may or
1200 may not work, depending on who made the Unix system. If the library
1201 libXol is part of the X distribution, then you have X11R3 and Emacs
1204 Most versions of V.4 support sockets. If `/usr/lib/libsocket.so'
1205 exists, your system supports them. If yours does not, you must add
1206 #undef HAVE_SOCKETS in config.h, after the inclusion of s-usg5-4.h.
1207 (Any system that supports Internet should implement sockets.)
1211 Recent versions of Ultrix appear to support the features of Berkeley 4.3.
1212 Ultrix was at the BSD 4.2 level for a long time after BSD 4.3 came out.
1214 Ultrix 3.0 has incompatibilities in its X library if you have the
1215 Ultrix version of X (UWS version 2.0). To solve them, you need to
1216 prevent XvmsAlloc.o in Xlib from being used. Israel Pinkas says:
1218 I added the following lines to config.h after the X defines:
1220 #if defined(ultrix) && defined(X11)
1221 #define OBJECTS_SYSTEM calloc.o
1224 Then I ran the following:
1226 ar x /usr/lib/libc.a calloc.o
1228 The problem is said to be gone in UWS version 2.1.
1230 Uniplus 5.2 (unipl5.2)
1232 Works, on Dual machines at least.
1236 Richard Levitte <levitte@e.kth.se> distributes a set of patches to
1237 Emacs 18.59 to make it work nicely under VMS. Emacs 19 probably
1238 won't work very well, or even compile. Levitte is working on a
1239 port, so these problems should be fixed in the near future.
1241 Note that Emacs for VMS is usually distributed in a special VMS
1242 distribution. See the file ../vms/VMSINSTALL for info on moving
1243 Unix distributions to VMS, and other VMS-related topics.
1247 Should work in 18.50, but you will need to edit the files
1248 `lib-src/Makefile' and `src/ymakefile'
1249 (see the comments that mention "Xenix" for what to change.)
1250 Compiling Emacs with -O is said not to work.
1252 If you want Emacs to work with Smail (installed as /usr/bin/smail)
1253 then add the line #define SMAIL to config.h.
1255 The file etc/XENIX suggests some useful things to do to Xenix
1256 to make the Emacs meta key work.
