Xos.h needs X11/Xw32defs.h ?? Missing??

[Alan Wong]

Hi, I've installed cygwin and xfree and built c/c++ application including
headers:

#include <X11/Xlib.h>
#include <X11/Xlibint.h>
#include <X11/Xutil.h>
#include <X11/Xatom.h>
#include <X11/Xos.h>

where I have C:\cygwin\usr\X11R6\include\X11 as an include directory.
So the compiler is happy until it hits line 138 of Xos.h:

#ifdef WIN32
#include <X11/Xw32defs.h>
#else

I can't seem to find this file anywhere.  Was it supposed to be part of the
install?
Am I missing a file?  How do I get it if I need it or what should I do??

Thanks.
