What are you concerned about, exactly? That we still fix the Sun version when
there is already a GCC version (harmless) or that we fix the GCC version
(wrong). In the former case I don't see the problem, in the latter case I'm
under the impression the solution is to strengthen the matching regexp, not
to loosen the bypass regexp.
