HP-UX/aCC, the only compiler in the buildfarm I found that seems to fall short 
in the "quiet inline" test.

MSVC seems to work fine with in supported versions, USE_INLINE is defined 
these days.

I propose to treat any compiler which has no way to get to equivalent 
behaviour as not sensible. Yes. I don't think there really are many of those 
around. As you pointed out there is only one compiler in the buildfarm with 
problems and I think those can be worked around (can't test it yet though, the 
only HP-UX I could get my hands on quickly is at 11.11...).
