[issue] __STDC_VERSION__ not defined warning on Mac OS X

I think this is an extremely unusual case restricted to a very specific platform/compiler combination, so I'm not planning to do anything about it, except post the workaround, below. Let me know if it seems worthy of more attention than that. On Mac OS X v.10.5.7 with the stock GCC, I get literally hundreds of these warnings: gcc -c -Wall -Wno-switch -Wundef -Wsign-compare -Wno-char-subscripts \ -Wpacked -Wpointer-arith -Wunused-parameter -g -Demacs \ -I. -I/Users/steve/src/XEmacs/sandbox/src -DHAVE_CONFIG_H \ -I/opt/local/include -I/opt/local/include \ -I/opt/local/include/freetype2 -I/usr/X11/include \ /Users/steve/src/XEmacs/sandbox/src/EmacsFrame.c In file included from /Users/steve/src/XEmacs/sandbox/src/number-gmp.h:43, from /Users/steve/src/XEmacs/sandbox/src/number.h:62, from /Users/steve/src/XEmacs/sandbox/src/lisp.h:3874, from /Users/steve/src/XEmacs/sandbox/src/EmacsFrame.c:30: /opt/local/include/gmp.h:427:74: warning: "__STDC_VERSION__" is not defined This is due to line 287 in gmp.h: #elif !(defined __APPLE__ && defined __MACH__ && __APPLE_CC__ >= 5465 && __STDC_VERSION__ >= 199901L) which is MacPorts brain damage, not from GMP itself (there's a patch in the MacPorts tree, so yes I'm sure). If you run into this, running CFLAGS=-D__STDC_VERSION__=0L ./configure ... (where ... is your usual set of flags to configure) will suppress these warnings, and should be safe. _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-beta
