/*

 */

/*
 * Mingw.org versions of the Windows API headers actually avoid
 * making the conflicting definitions if XFree86Server is defined, so we
 * need to remember if that was defined and undefine it during including
 * windows.h (so the conflicting definitions get wrapped correctly), and
 * then redefine it afterwards. (This was never the correct thing to
 * do as it's no help at all to X11 clients which also need to use the
 * Win32 API)
