Yep, it would.

I think that any such mechanism would need to be wrapped with
a BOOST_TESTED_AT(...) to make sure that real warnings highlighted by
new versions of the compiler didn't sneak through. It isn't reasonable
to assume that the library author will immediately test all new GCC
releases with the pragma disabled.
