Guys, how to get a look at this bug? I'm tired of reading 100500 warnings from
third-party libraries.

GCC-4.6, GCC-4.7, GCC-4.8, C++11
Gentoo Linux x86-64

The C++ parser lexes (and preprocesses) before handling the pragmas, whereas
the C parser processes the pragmas as it sees them.

We must somehow parse these pragmas *also* in cp/parser.c:631. Maybe one can do
something similar to what we do for cp_parser_initial_pragma, but within the
loop and only handling pragma diagnostic. Surely, it will need some trial and
error to get it right. If any of you wants to give it a try and need some help,
just ask here or in the mailing list.
