Subject: compiling xterm from cvs

Hi list

I would like to compile xterm with debugging symbols to get a better idea of
how ptys can be used under Cygwin
(http://cygwin.com/ml/cygwin/2003-07/msg01270.html).

I got the source from CVS as described on http://xfree86.cygwin.com/cvs.html

The configure script, as described in the xc/programs/xterm/INSTALL file,
runs without any errors.  However, running make on the Makefile it
generates, I get the following:

gcc -I. -I. -DHAVE_CONFIG_H  -I/usr/X11R6/include -D__i386__
-DWIN32_LEAN_AND_MEAN -DX_LOCALE -D_X86_  -DNO_TCP_H -D__CYGWIN__
-D_XOPEN_SOURCE -D_POSIX_C_SOURCE=199309L -D_BSD_SOURCE -D_SVID_SOURCE
-D_GNU_SOURCE -DFUNCPROTO=15 -DNARROWPROTO -I.     -DPROJECTROOT=/usr/X11R6
-DUTMP  -DOSMAJORVERSION=1 -DOSMINORVERSION=3  -I/usr/X11R6/include  -g -O2
-c ./button.c

                 from ptyx.h:69,
                 from xterm.h:232,
                 from button.c:62:

/usr/lib/gcc-lib/i686-pc-cygwin/3.2/include/stddef.h:296: previous
declaration of `wchar_t'
make: *** [button.o] Error 1

I have the most recent "Curr" release from setup of all X11 and Base
packages.

Is there some incompatibility between X11 and standard headers in Cygwin?
That doesn't seem very plausible.  What is the correct way to go about this?
Thanks in advance for any suggestions you can offer.
