Don't you also need to set CPPFLAGS too, in general? Otherwise how will programs that run the preprocessor get the correct values for symbols like LONG_MAX? It does sound pretty inconvenient. I use something like CC='gcc -m64' CXX='g++ -m64', but that's not much better, and probably also has flaws. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
