* Problems with running XEmacs
==============================
** General
+*** gnuserv is running, some clients can connect, but others cannot.
+
+The code in gnuslib.c respects the value of TMPDIR. If the server and
+the client have different values in their environment, you lose.
+One program known to set TMPDIR and manifest this problem is exmh.
+You can defeat the use of TMPDIR by unsetting USE_TMPDIR at the top of
+gnuserv.h at build time.

*** C-z just refreshes the screen instead of suspending Emacs.
You are probably using a shell that doesn't support job control, even
Try evaluating the form (setq lock-directory nil) and see if that helps.
There is a problem with file-locking on some systems (possibly related
to NFS) that I don't understand. Please send mail to the address

+**** XEmacs warns "Symbol `toggleClassRec' has different size in shared
+ object, consider re-linking / Symbol `labelClassRec' has different
+ size in shared object, consider re-linking / Warning: Representation
+ size 4 must match superclass's to override value"
+
+Sometimes this results in segfaults when using the tab control widget
+or a progress bar widget.
+
+Some versions of Debian install 3D versions of the Athena widget
+library as /usr/X11R6/lib/libXaw.so. We have not yet solved the
+problem of identifying the actual library in use in ./configure, so it
+is possible for XEmacs to be compiled with reference to headers for
+"flat" Xaw but find a "3D" Xaw when loading.
+
+The straightforward solution is to rebuild XEmacs with additional
+configure options: --with-widgets=athena --with-athena=3d.
+
+There are several 3D Athena widget sets available; to see which ones
+are supported by XEmacs, use ./configure --usage.

*** Mandrake
The Mandrake Linux distribution is attempting to comprehensively
The color-gcc wrapper (see below) is in common use on the Mandrake
platform.
+*** XEmacs configured with ESD crashes with a segmentation violation
+
+This often occurs when a progress bar pops up.
+
+The problem is that the ESD sound daemon manipulates interrupts in a
+way that disagrees with XEmacs. The currently available workaround is
+not very satisfactory: remove ESD support. Rebuild after
+reconfiguring with the option --with-sound=none[,native][,nas]
+
+The funny syntax (requiring the initial "none") is for backward
+compatibility, and may change. Native sound and NAS do not cause the
+problem, so they may be added to the option to get some sound support.

*** I want XEmacs to use the Alt key, not the XXX key, for Meta commands
For historical reasons, XEmacs looks for a Meta key, then an Alt key.
solution above is insufficient, because getaddrinfo() by default tries
to get IPv6 information for localhost. This always involves a dns
lookup to get the CNAME, and the strategies above don't work. It then
