Re: Fortran 95 compiler

I mostly stole them from newer versions of GCC :-)
the failures for newer FSF GCC (what pkgsrc has) seems to be libgcc
getting misconfigured.

I did see something interesting in the gcc7.1 linux--powerpc libgcc
configure script, where it'd pick float choice based on existing
compiler float options.

on powerpc and ARM, I get something like this:

on GCC 7.1 and mips64 I get:
(this one looks like it might be some command line tool differences,
gsed vs. nbsed?)
