There's odd bits code scattered around in Sage that do tests for g95, which is
an old Fortran 95 compiler that in any modern Linux or Unix systems.
According to Wikipedia
http://en.wikipedia.org/wiki/G95
gfortran was forked from g95 in 2003 - i.e. 7 years ago.
I'm not sure at what point gfortran became the dominant compiler, but I've not
seen g95 used in the last few years. It might still exist on some systems, but
people tend to use gfortran instead, as that is part of gcc.
Do others, like me, believe we just remove such bits of code as and when we come
across them? i.e. don't make specific tests for gfortran vs g95?
g95 binaries have already been removed from Sage

There's a few bits of code in the ATLAS package which make such tests - one of
them uses the "readelf" program to determine if a pre-installed version of ATLAS
was built with g95.

"Probably the only platforms that get g95 are older OS X."
Since ATLAS is not installed on OS X, it seems even less worthwhile having such
a test in the ATLAS package.
But before removing this code, I thought it wise to get the opinion of others.
