This seems like a fair amount of extra configure tests. Particularly because
/W* isn't ever interesting for Makefile.global - they're msvc flags - because
you can't use that with msvc.
I'm also doubtful that it's worth supporting warning_level=3/everything, you
end up with a completely flood of warnings that way.
