/* Note that there are currently FOUR different general
   Windows-related include files in src!

   Uses are approximately:

   syswindows.h: Mostly a wrapper around <windows.h>, including missing
   defines as necessary.  Also includes stuff needed on both Cygwin and
   native Windows, regardless of window system chosen.

   console-msw.h: Used on both Cygwin and native Windows, but only when
   native window system (as opposed to X) chosen.

   nt.h: [will be renamed to win32.h] Used only on native Windows, and
   regardless of window system chosen -- but used on both purely native
   Windows (s/windowsnt.h) and MinGW (s/mingw32.h).

   ntheap.h: Used only on native Windows and only when standard dumping
   mechanism (unexnt.c) used.

   All of the last three files include the first.
