For example, I'm currently writing a library that uses C99 inline.  Compiling 
with GNU C89 inline would probably be very bad; if it works, I wouldn't trust 
that code.  (okay, I know there's -fno-gnu89-inline; but I just want to be on 
the safe side, and disallow C89/GNUC89 entirely).

Cheers,

Alex
