24 /* The following line tells the configuration script what sort of
25 operating system this machine is likely to run.
29 We are in the dark about what operating system runs on the Whitechapel
30 systems. Consult share-lib/MACHINES for information on which
31 operating systems Emacs has already been ported to; one of them might
32 work. If you find an existing system name that works or write your
33 own configuration files, please let the Free Software Foundation in on
34 your work; we'd like to distribute this information.
37 /* Now define a symbol for the cpu type, if your compiler
38 does not define it automatically:
39 vax, m68000, ns16000, pyramid, orion, tahoe and APOLLO
40 are the ones defined so far. */
41 /* Say this machine is a 16000 and an mg1, cpp says its a 32000 */
45 /* Data type of load average, as read out of kmem. */
46 /* mg1 its an unsigned long */
47 #define LOAD_AVE_TYPE unsigned long
49 /* Convert that into an integer that is 100 for a load average of 1.0 */
51 #define LOAD_AVE_CVT(x) (int) (((double) (x)) * 100.0 / FSCALE)
53 /* Define CANNOT_DUMP on machines where unexec does not work.
54 Then the function dump-emacs will not be defined
55 and temacs will do (load "loadup") automatically unless told otherwise. */
56 /* ns16000's have an unexec, so should the mg-1 */
59 /* Define C_ALLOCA if this machine does not support a true alloca
60 and the one written in C should be used instead.
61 Define HAVE_ALLOCA to say that the system provides a properly
62 working alloca function and it should be used.
63 Define neither one if an assembler-language alloca
64 in the file alloca.s should be used. */
65 /* hmmmm... again not sure. so copied sequent.h again! */
69 /* Define NO_REMAP if memory segmentation makes it not work well
70 to change the boundary between the text section and data section
71 when Emacs is dumped. If you define this, the preloaded Lisp
72 code will not be sharable; but that's better than failing completely. */
73 /* mapping seems screwy */
76 /* Avoids a compiler bug */
