But its C++ support is just starting.
And if you're just interrested in a C++ parser, then i would point at boost::wave (didn't look if clang uses wave or not, i'd guess it could). _______________________________________________ Tinycc-devel mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/tinycc-devel
