 *      MACROS for Mac/PC core code
 *
 *      The following macros reduce the proliferation of #ifdefs.  They
 *      allow tagging a fragment of code as Mac only, PC only, or with
 *      variants which differ on the PC and the Mac.
 *
 *      Usage:
 *
 *
 *      h = GetHandle();
 *      Mac(DisposeHandle(h));
 *
 *
 *      h = GetHandle();
 *      MacWin(h2 = h, CopyHandle(h, h2));
