From an autoconf point of view, you probably shouldn't be messing with CXXFLAGS -- that's a variable that the user should be setting. >From a shell point of view, the program: CXXFLAGS="-D__int64=\"long long\"" for i in $CXXFLAGS; do echo $i; done outputs: -D__int64="long long" which may help to explain the symptoms you're seeing. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
