Emmanuele Bassi 20b2e479f8 build: Add various compiler warnings and errors 
Just like GLib, GTK+ would benefit from getting warnings and errors from
the compilers.

We check various, common warnings, especially for a future use of C99;
additionally, we promote some warnings to errors, in order to ensure
that simple mistakes are caught during the development phase, before
they are submitted to the code repository.
