From initial skimming it looks like it is only parse.y that doesn't honor warnings_are_errors, because it does the diagnostics by hand.

This seems to have never been pushed upstream and never been tested as a fix. In Fedora rawhide parse.y doesn't exist anymore. But the above still doesn't work because of bug #231020 which makes -Werror an invalid flag.
The bug is present in all pre Java 1.5 GCJ versions. GCC4 on RHEL 4, and GCC on RHEL 5 and FC-6 for instance. You may want to clone this against those distro-s and push through fixes. Alternatively you could make Java 1.5 GCJ available there.
