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 **
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.
25 DARWIN_OS       Compiling on Mac OS X or pure Darwin (and using s/darwin.h).
26 SOLARIS2
27 USG
28 USG5_4
30 ** Distinguishing GUIs **
32 HAVE_NTGUI      Use the native W32 GUI for windows, frames, menus&scrollbars.
33 HAVE_NS         Use the NeXT/OpenStep/Cocoa UI under Mac OS X or GNUstep.
34 NS_IMPL_GNUSTEP Compile support for GNUstep implementation of NS GUI API.
35 NS_IMPL_COCOA   Compile support for Cocoa (Apple) implementation of NS GUI API.
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
43 HAVE_X11XTR6
44 USE_LUCID       Use the Lucid toolkit for menus&scrollbars.  Requires HAVE_X11.
45 USE_MOTIF       Use the Motif toolkit for menus&scrollbars.  Requires HAVE_X11.
46 USE_GTK         Use the Gtk   toolkit for menus&scrollbars.  Requires HAVE_X11.
48 ** Frame types **
50 FRAME_TERMCAP_P A tty (character terminal) frame.
51 FRAME_X_P       A frame on X Window system.
52 FRAME_MSDOS_P   An MS-DOS frame (used only by the DOS port).
53 FRAME_W32_P     A frame using native MS-Windows GUI.
54 FRAME_WINDOW_P  A GUI frame (like X, w32, etc.)
56 ** Support for accessing other processes on the system **
58 HAVE_PROCFS     The /proc filesystem is supported.
60 ** Compile-time options **
62 REL_ALLOC       Compile in the relocatable memory allocator ralloc.c.
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.
66 DEBUG_LISP_OBJECT_TYPE Define it in lisp.h enable compile time checks
67                        on Lisp_Object use.
69 ** System specific macros
70 FIRST_PTY_LETTER
71 HAVE_PTYS
72 INTERRUPT_INPUT
73 NARROWPROTO
74 SEPCHAR
75 SYSTEM_TYPE
77 ** Misc macros
78 USER_FULL_NAME   If defined, overrides the default pw->pw_gecos for
79 getting at the full user name.  Only MSDOS overrides the default.
81 ** Miscellaneous defines.  Some of these might not be used in the code
82 anymore, so they can be removed.
