+This may be because you are using the default cygwin shell. The

+text mode when working with source vs. binary files, which overrides

+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.

+*** 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.
A newer problem is due to XEmacs changing to use the modern
getaddrinfo() interface from the older gethostbyname() interface. The
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
-falls back to IPv4 behavior. This is good[tm]; trust us.

-getaddrinfo() is also called in src/sysdep.c:init_system_name() and in
-src/process-unix.c:unix_open_network_stream(). It should not be
-useful to make this change in either of those places.
+If esd is not running (e.g. you unchecked the run esd checkbox in the
+GNOME Configuration tool), every sound event will cause the esound
+client library to signal SIGUSR1. It is not that difficult (hold down
+PgUp or PgDn, for example) to cause XEmacs to generate additional
+SIGUSR1 signals before the first handler has a chance to reset, so the
+second SIGUSR1 causes the default behavior of ending the process.
+The solution is either to build XEmacs with -sound=native,noesd or to make sure
+that esd is in fact running.
