This is obvious; please do commit it. I'm all in favor of debug info
Of course, we may want to mark it XFAIL if we end up stopping where
broken GCC's would have; I really dislike FAILs that GDB can do nothing
about, although in some cases they're unavoidable. Do we have a
documented policy for what all the DejaGNU result codes mean in the GDB
testsuite? If not, should I propose one?
