To be precise, what it checks for is excess messages output to stderr. It
doesn't discriminate whether they are errors, warnings, or a debugging printf
that you accidentally left in when you compiled!

I can't say.

Hmmm, that's a problem. We don't really want to be testing the assembler's
or linker's output. Don't immediately know how you'd get round that without
reworking the testsuite to run the various substages of the compilation
one-at-a-time, or just adding horrible hard-coded filtering to the captured
stderr output...
Actually, I wonder if "-Wl,2> -Wl,/dev/null" would work!? (modulo suitable
quote/escaping).
