You can grep for flag_permissive and permerror in the source code. Also, if you use -fdiagnostics-show-option with gcc 4.4 it will tell you if an error may be disabled using -fpermissive. In general the gcc maintainers provide -fpermissive to make it possible to compile older non-standard-compliant code, but discourage its use. Ian
