[Mingw-msys] Problem building XEmacs

[Andrew B. <ab...@ee...>]

I'm trying to configure XEmacs with MSYS. Part of the configure script
does this:

cat > $tempcname < confdefs.h
cat >> $tempcname <<EOF
#define NOT_C_CODE
#define C_SWITCH_SITE
#define C_SWITCH_X_SITE
#define LD_SWITCH_SITE
#define LD_SWITCH_X_SITE
#define LD_SWITCH_X_SITE_AUX
#define OS_RELEASE $os_release

#ifdef config_opsysfile
#include "$srcdir/src/$opsysfile"
#endif

#ifdef config_machfile
#include "$srcdir/src/$machfile"
#endif

Where $srcdir is an MSYS path. It's put directly into a #include and
then passed to MinGW's gcc. But gcc can't read MSYS paths when found in
#includes.=20

Is there a good way to rewrite this form to work in MSYS?
