--- Comment #52 from Martin Sebor <msebor at gcc dot gnu.org> --- -Wnull-dereference is a language-independent option (it works for C, C++, and should work for all other languages). But this bug isn't the right forum to discuss general GCC usage questions (such as why -Q --help=warnings,C doesn't print some C language options). Please either raise those on the gcc-help list or open new bugs for suspected problems.
