OK for mainline (and for 4.2 if you backport the .f03 support patch),  
with one detail: I'd also like you to add .f03 to libgomp/testsuite/ 
libgomp.fortran/fortran.exp, for consistency. Please add this bit and  
regtest, then send the final patch to Richard Henderson  
(rth@redhat.com) for him to approve the libgomp part.

Thanks,
FX
