Pragmatically, that works (as I'm sure you know).   Digging into the  
legalities of C99 I'm not sure that it's guaranteed to work, though.    
Unknown directives actually match the "non-directive" case in the  
grammar in 6.10; while nothing is said anywhere about semantics that I  
can find, I'm not sure why gcc feels this should be a hard error at  
all....
