admin/CPP-DEFINES

   1 Here are some of the cpp macros used, together with some short explanation
   2 of their use.  Feel free to add more macros and more categories.
   3 Most of these are from config.in, so it's probably better to put the
   4 explanations in that file.  Ideally, everything would be defined and
   5 documented in config.in, and this file would not be necessary.

   8 ** Distinguishing OSes **
   9
  10 AIX
  11 _AIX
  12 CYGWIN          Compiling the Cygwin port.
  13 __CYGWIN__      Ditto
  14 GNU_LINUX
  15 HPUX
  16 IRIX6_5
  17 MSDOS           Compiling the MS-DOS port.
  18 __MSDOS__       Ditto.
  19 __DJGPP_MINOR__ Minor version number of the DJGPP library; used only in msdos.c and dosfns.c.
  20 DOS_NT          Compiling for either the MS-DOS or native MS-Windows port.
  21 WINDOWSNT       Compiling the native MS-Windows (W32) port.
  22 __MINGW32__     Compiling the W32 port with the MinGW or MinGW-w64 ports of GCC.
  23 _MSC_VER        Compiling the W32 port with the Microsoft C compiler.
  24 MINGW_W64       Compiling the W32 port with the MinGW-w64 port of GCC.

  30 ** Distinguishing GUIs **
  31
  32 HAVE_NTGUI      Use the native W32 GUI for windows, frames, menus&scrollbars.

  36 HAVE_X11        Compile support for the X11 GUI.
  37 HAVE_X_WINDOWS  Compile support for X Window system
  38   (It looks like, nowadays, if HAVE_X11 is set, HAVE_X_WINDOWS must
  39    be, and vice versa.  At least, this is true for configure, and
  40    msdos; not sure about nt.)
  41 HAVE_X11R6
  42 HAVE_X11R6_XIM

  63 SYSTEM_MALLOC   Use the system library's malloc.
  64 subprocesses    System can use subprocesses (for M-x shell for example).
  65                 Defined by default, only MSDOS undefines it.
