It is sometimes useful to be able to detect the compiler version (as in the case of GCC 4.2 doing some fairly aggressive optimization that breaks fragile code).
How about something like: AC_GCC_VERSION(VER, MATCHING-VERSION, [ NON-MATCHING-VERSION ]) so I could do something like: AC_GCC_VERSION(4.2, [OPTIMIZE =], [OPTIMIZE = -O2]) Then I could avoid: http://svnview.digium.com/svn/asterisk/branches/1.4/codecs/gsm/Makefile?r1=285817&r2=285816&pathrev=285817 Thanks. -Philip
