Hi,
I tried adding --enable-install-setuid --enable-debug

xorg-server-X11R7.1-1.1.0: ./configure CFLAGS="-g -O0" \
   --with-mesa-source=/home/russell/SRC/Mesa-6.5 --enable-install-setuid --enable-debug

but i get new errors:

The first error comes from:
   xorg-server-X11R7.1-1.1.0/hw/xfree86/common/xf86Debug.c:48

_X_EXPORT void xf86Break1(void)
{
}

/usr/local/include/X11/Xfuncproto.h:

#if defined(__GNUC__) && ((__GNUC__ * 100 + __GNUC_MINOR__) >= 303)

I've installed fixesproto-X11R7.1-4.0 and xproto-X11R7.1-7.0.5 into /usr/local,
and have PKG_CONFIG_PATH="/usr/local/lib/pkgconfig".
