I don't think there is a list.  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.
