For existing warnings, we try and match GCC's flag names.  For new warnings being added to Clang that (to our knowledge) aren't being added to GCC, there is no dialog with the GCC developers to support the same warning flag.  I think dialog between the communities would be helpful in this regard, but I'm not interested in establishing an official process here for coordinating warnings between the two compilers.  Generally speaking it hasn't been a problem at all, and that formal process would likely burden both communities.
