Hi

I'm copying this from the xemacs-beta list.

I see this problem too.

This is a result of interaction between four packages under cygwin: xemacs,
gcc, autoconf and x11.

The version of X11 that Volker and I have installed under cygwin contains
the following line in /usr/X11R6/lib/X11/config/cygwin.cf

#define StandardDefines         -D__i386__ -DWIN32_LEAN_AND_MEAN -DX_LOCALE -D_MT -D_X86_ -D__STDC__ -DNO_TCP_H -D__CYGWIN__ -D_XOPEN_SOURCE -D_REENTRANT -D_POSIX_C_SOURCE=199309L -D_BSD_SOURCE -D_SVID_SOURCE -D_GNU_SOURCE

(It seems totally bogus to me. Why are __STDC__ and __CYGWIN__ being -D'ed
from the command line?)

XEmacs's configure script takes the -D__STDC__ and transforms it into a
`#define __STDC__ 1' line in its confdefs.h.

gcc 2.95.2 did not complain about __STDC__ being redefined in confdefs.h
gcc 2.95.3 gives a warning. The configure script (autoconf, really)
interprets the warning as an indication that X11/Intrinsic.h doesn't exist.
Hence the error.

Off the top of my head, here are some ideas for fixing the problem,
- fix X11's cygwin.cf. Does cygwin-xfree have this problem?
- fix autoconf to ignore warnings when determining the existing of header
  files.
- change XEmacs's configure script so that it doesn't add __STDC__ to
  confdefs.h

Does anyone have any other ideas? Does this problem show up on any systems
other than cygwin?
