Thanks. I would encourage you to file an enhancement request at http://gcc.gnu.org/bugzilla/ . > I've found out that the present warning is done in "c-typeck.c", > is this the right place to but additional warnings of this kind too? Since these sorts of errors can occur in both C and C++ it would be slightly better to use a common framework for them if possible, perhaps in c-family/c-common.c. I haven't really thought about what is required here, though. Ian
