** Distinguishing OSes **
-MAC_OS Compiling for some version of Mac OS?
-MAC_OS8 Compiling for Mac OS version 8. Requires MAC_OS?
-MAC_OSX Compiling for Mac OS X? Is that also valid for Darwin?
-MAC_OS_X ?? Apparently only used once in mac.c.
CYGWIN Compiling the Cygwin port.
__CYGWIN__ Ditto
MSDOS Compiling the MS-DOS port.
WINDOWSNT Compiling the native MS-Windows (W32) port.
__MINGW32__ Compiling the W32 port with the MinGW port of GCC.
_MSC_VER Compiling the W32 port with the Microsoft C compiler.
+DARWIN_OS Compiling on Mac OS X or pure Darwin (and using s/darwin.h).
** Distinguishing GUIs **
HAVE_NTGUI Use the native W32 GUI for windows, frames, menus&scrollbars.
-HAVE_CARBON Compile support for the Carbon GUI. Requires MAC_OS?
+HAVE_NS Use the NeXT/OpenStep/Cocoa UI under Mac OS X or GNUstep.
+NS_IMPL_GNUSTEP Compile support for GNUstep implementation of NS GUI API.
+NS_IMPL_COCOA Compile support for Cocoa (Apple) implementation of NS GUI API.
HAVE_X11 Compile support for the X11 GUI.
HAVE_X_WINDOWS Compile support for X Window system
X11 ?? Makefile.in suggests it's equivalent to HAVE_X11
FRAME_TERMCAP_P A tty (character terminal) frame.
FRAME_X_P A frame on X Window system.
FRAME_MSDOS_P An MS-DOS frame (used only by the DOS port).
-FRAME_MAC_P A Mac frame.
FRAME_W32_P A frame using native MS-Windows GUI.
FRAME_WINDOW_P A GUI frame (like X, w32, etc.)
+** Support for accessing other processes on the system **
+
+HAVE_PROCFS The /proc filesystem is supported.
+
** Compile-time options **
+
REL_ALLOC Compile in the relocatable memory allocator ralloc.c.
SYSTEM_MALLOC Use the system library's malloc.
+subprocesses System can use subprocesses (for M-x shell for example). Defined by default, only MSDOS undefines it.
+USE_LISP_UNION_TYPE Define it in lisp.h to make Lisp_Object be a union type instead of the default int.

+** Not used anymore by any port, can be cleaned up
+NO_SOCK_SIGIO
-ADJUST_EXEC_HEADER
+** Misc macros
+USER_FULL_NAME If defined, overrides the default pw->pw_gecos for getting at the full user name. Only MSDOS overrides the default.
+
+** Replace, the definition is trivial: SWITCH_ENUM_CAST
+
+** 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.
