/* 
   A capsule introduction to Windows-related build flags:

   See also: (Info-goto-node "(internals)Windows Build Flags")

   1. Operating-system level:
   --------------------------

   `CYGWIN'	Compiled for Cygwin.  Cygwin provides a full Unix-like
		environment under Windows.  Applications compiled for Cygwin
		are linked with CYGWIN1.DLL, which provides the POSIX
		emulation.

		Corresponding s/ file: s/cygwin32.h

   `MINGW'	Compiled for MinGW.  MinGW is a Unix-like environment under
		Windows that allows for the use of `gcc' to create fully
		native Windows applications that link with the normal
		Microsoft C-runtime library (e.g. MSVCRT.DLL), and don't
		require a special POSIX-emulation DLL (e.g. CYGWIN1.DLL).
		Conversely, the only POSIX-like services available are
		those in MSVCRT.DLL, which isn't much.  Essentially, coding
		for MinGW is identical to coding for native Windows using
		Visual C++ or the like, whereas coding for Cygwin is like
		coding for Linux, but with the additional possibility of
		making Win32-API calls.  Additional confusion comes from
		the fact that you can use the Cygwin environment and
		compilers to build a MINGW application (e.g. by passing the
		`-mno-cygwin' command-line argument to `gcc').

		Corresponding s/ file: s/mingw32.h

   (none)	There's no flag to indicate that you are specifically
		targeting native Windows and not doing this with MINGW.
		Presumably this means you're using Visual C++.

		Corresponding s/ file: s/windowsnt.h

   `WIN32_ANY'	Any of the above three environments.

		Corresponding s/ file: s/win32-common.h

   `WIN32_NATIVE'
		Native Windows target, either MinGW or Visual C++.
                That is, not Cygwin.

		Corresponding s/ file: s/win32-native.h


   2. Compiler level:
   ------------------

   `__GNUC__'	Defined whenever compiling with gcc (Cygwin or MinGW).

   `_MSC_VER'	Defined whenever compiling with Visual C++.

   `CYGWIN_HEADERS'
		Defined whenever using Cygwin-style header files rather
		than Visual C++ headers.  Currently this means the same
		as "Cygwin or MinGW" and the same as "compiling with gcc".
		This applies especially to the header files in
		/usr/include/w32api, which is a free replacement for the
		standard Visual C++ headers for the Win32 API.


   3. Window-system level:
   -----------------------

   `HAVE_MS_WINDOWS'
		MS Windows native windowing system (anything related to the
		appearance of the graphical screen).  May or may not apply
		to any of VC++, MinGW, or Cygwin.  For example, it's
		definitely possible to compile XEmacs under Cygwin with
		support for X-Windows frames and TTY frames, but no
		native MS Windows frames.  It may also be possible to do that
		under MinGW or (less likely, but feasible) Visual C++.
   
   `HAVE_X_WINDOWS'
		Support for X-Windows frames, regardless of whether under
		MS Windows.  You can certainly compile XEmacs with support
		for X-Windows frames when running on MS Windows, using Cygwin.

   `HAVE_GTK', `HAVE_TTY'
		Likewise.  All are available on MS Windows with Cygwin.

    Note further that more than one of these can be defined at the same time.
    In fact, in general, it's possible to compile with support for all of
    these at the same time.



   Here is a table mapping from GNU Emacs constants to XEmacs constants for
   use in porting code.
 

   Old Constant       New Constant
   ---------------------------------------------------------------
   `WINDOWSNT'        `WIN32_NATIVE'
   `WIN32'            `WIN32_NATIVE'
   `_WIN32'           `WIN32_NATIVE'
   `HAVE_WIN32'       `WIN32_NATIVE'
   `DOS_NT'           `WIN32_NATIVE'
   `HAVE_NTGUI'       `WIN32_NATIVE', unless it ends up already bracketed
                      by this
   `HAVE_FACES'       always true
   `MSDOS'            determine whether this code is really specific to
                      MS-DOS (and not Windows - e.g. DJGPP code); if so,
                      delete the code; otherwise, convert to `WIN32_NATIVE'
                      (we do not support MS-DOS w/DOS Extender under XEmacs)
   `__CYGWIN__'       `CYGWIN'
   `__CYGWIN32__'     `CYGWIN'
   `__MINGW32__'      `MINGW'
