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.
4 ** Distinguishing OSes **
6 CYGWIN Compiling the Cygwin port.
8 MSDOS Compiling the MS-DOS port.
10 __DJGPP__ Major version number of the DJGPP library for the DOS port.
11 __DJGPP_MINOR__ Minor version number of the DJGPP library.
12 __GO32__ Compiling the DOS port with DJGPP v1.x (obsolete).
13 DOS_NT Compiling for either the MS-DOS or native MS-Windows port.
14 WINDOWSNT Compiling the native MS-Windows (W32) port.
15 __MINGW32__ Compiling the W32 port with the MinGW port of GCC.
16 _MSC_VER Compiling the W32 port with the Microsoft C compiler.
17 DARWIN_OS Compiling on Mac OS X or pure Darwin (and using s/darwin.h).
19 ** Distinguishing GUIs **
21 HAVE_NTGUI Use the native W32 GUI for windows, frames, menus&scrollbars.
22 HAVE_NS Use the NeXT/OpenStep/Cocoa UI under Mac OS X or GNUstep.
23 NS_IMPL_GNUSTEP Compile support for GNUSTEP implementation of NS GUI API.
24 NS_IMPL_COCOA Compile support for Cocoa (Apple) implementation of NS GUI API.
25 HAVE_X11 Compile support for the X11 GUI.
26 HAVE_X_WINDOWS Compile support for X Window system
27 X11 ?? Makefile.in suggests it's equivalent to HAVE_X11
28 USE_LUCID Use the Lucid toolkit for menus&scrollbars. Requires HAVE_X11.
29 USE_MOTIF Use the Motif toolkit for menus&scrollbars. Requires HAVE_X11.
30 USE_GTK Use the Gtk toolkit for menus&scrollbars. Requires HAVE_X11.
34 FRAME_TERMCAP_P A tty (character terminal) frame.
35 FRAME_X_P A frame on X Window system.
36 FRAME_MSDOS_P An MS-DOS frame (used only by the DOS port).
37 FRAME_W32_P A frame using native MS-Windows GUI.
38 FRAME_WINDOW_P A GUI frame (like X, w32, etc.)
40 ** Support for accessing other processes on the system **
42 HAVE_PROCFS The /proc filesystem is supported.
43 LISTPROC A function that returns a list of PIDs of system processes.
44 PROCATTR A function that returns attributes of a process.
46 ** Compile-time options **
48 REL_ALLOC Compile in the relocatable memory allocator ralloc.c.
49 SYSTEM_MALLOC Use the system library's malloc.
50 subprocesses System can use subprocesses (for M-x shell for example). Defined by default, only MSDOS undefines it.
51 USE_LISP_UNION_TYPE Define it in lisp.h to make Lisp_Object be a union type instead of the default int.
53 ** Replace, the definition is trivial: SWITCH_ENUM_CAST
55 ** Defines from src/m/*.h and src/s/*.h. Some of these might not be used in the code anymore, so they can be removed. The HAVE_* definitions are probably handled by autoconf, so it might be possible to just remove them from src/[sm]/*.h.
