When we build R on our Build System machines, we let the 'configure' script
pick up the right compilers for us.
The default search for the Fortran compiler is described here
So, g77 will be picked up on a Linux systems with gcc 3 (e.g. SUSE 9.2) and
it will be gfortran on a Linux system with gcc 4 (e.g. SUSE 10.0).
Compare the BUILD output for the DNAcopy package on gopher5 (SUSE 9.2)
vs gladstone (SUSE 10.0):
To make this more clear, more details about the platforms used on our
Build System machines will be available on the build/check report soon...
Thanks for your feedback.
