[Rd] R 2.1 and gfortran

 From the configure output of the latest devel snapshot:

The Fortran compiler in gcc-4.0 defaults to the name 'gfortran'.   
Other packages such as Octave seem to check for that.

Just to suggest that gfortran should be added to the list of possible  
compilers.

As a footnote I have built R 2.1 on MacOS X using a compiler built  
from very recent Apple cvs sources, with patches from the gfortran  
cvs code up to 18th May.  This binary passes all the tests.
