YIKES -- The *right* way todo this is to just change the configure.ac
files to NOT check for 'X' and NOT include the X_Header path when
WIN32 is defined.
Obviously this change needs tobe done by someone who has the
Cygwin X-Server installed
There is support in the script already to determine if this
is a Windows installation.
My WAG is that perhaps changing
if test "x$HOSTTYPE" != "xmacintosh" -a "x$is_mingw" != "xyes"; then
dnl extra library and include directories
EXTRA_DIRS="/usr/X11R6"
if test -d /opt/X11R6 ; then
EXTRA_DIRS="$EXTRA_DIRS /opt/X11R6"
fi
fi
TO
if test "x$HOSTTYPE" != "xmacintosh" -a "x$is_mingw" != "xyes" -a
:x$is_cywin"!="xyes"; then
dnl extra library and include directories
EXTRA_DIRS="/usr/X11R6"
if test -d /opt/X11R6 ; then
EXTRA_DIRS="$EXTRA_DIRS /opt/X11R6"
fi
fi
Might just work, but I am not an autoconf guru nor do I have X installed
so I can not test this
FWIW - I am not sure about the multiple '-a' arg to if 'if test'
