[Bug c/15450] New: Ability to turn selected warnings into errors.

["niqueco at hotmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Usually turning -Werror is too much, someone could want to just turn some
warnings into errors. The example that is triggering this request is:

a.c:3: warning: data definition has no type or storage class

with this code:

-------------------------
<at top level!>
some_variable = NULL;
-------------------------

The arch is 64 bits, and sizeof(int) != sizeof(void*), ie. this crashed the program.

I'd like to be able to turn this warning to an error. This would have saved me a
lot of time.

Thanks!
