Hello, is there a simple macro that will test for a specific compiler flag and set a variable in both Makefile and config.h? I am looking for an easy way to test for GCC's -fvisibility=hidden and have an indicator whether or not it is available in said files. Thanks, Jan Engelhardt -- _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
