No, that is GNU Fortran 4.2.4 that I was referring to. The "gcc  
version 4.2.1" comes from Apple's Xcode 3.1 gcc-4.2 branch since that  
is what they define - it just adds Fortran support to the existing gcc  
4.2.1 branch of Apple that you installed as Xcode. However, the  
Fortran part is merged from the GNU Fortran 4.2.4 release - hence I  
refer to it as 4.2.4.

Cheers,
Simon
