Some of us are using much older gcc's than that, too ;-). But actually
I think this test is 100% bogus anyhow. What it appears to rely on is
the compiler failing to do semantic error testing on an inline function
that it doesn't need to instantiate. That's a behavior that I'm pretty
sure is gcc-specific rather than required by C99, and in any case has
very little to do with our requirements.
