What a surprise.

I've never understood the need for this {{{SAGE_FORTRAN}}}. I've tried
arguing for it to be removed and use {{{FC}}} instead, but I had no luck.
A Fortran compiler is still shipped on OS X, but I don't see why the
variable {{{FC}}} can't be made to point to that, rather than have the
variable {{{SAGE_FORTRAN}}}.

On Solaris, and some OS X versions, if you want a 64-bit build, you must
add the compiler flag {{{-m64}}} with gcc. Usually, putting that in
{{{CFLAGS}}} is enough. However, for Numpy that does not work.
Someone came up with a fix for this which was implemented only on OS X,
that involved creating a wrapper script called {{{gcc_fake}}} which
basically calls gcc with the {{{-m64}}} option. You can see the script
yourself in the top level directory.
Since they had done this only on OS X, it did not work on Solaris. So I
came up with a solution for Solaris, but I avoided the wrapper script.
Instead I set the variable to {{{CC=gcc -m64}}}
I'm attaching a patch, which basically uses the Solaris on any system,
including OS X. I think this is the sensible way to do it, not have a
wrapper script.
'''I've not tested the attached patch''' - not even on Solaris!! But I
think you can see what I am trying to do. I was going to try to explain it
in words, but a bit of code, even if untested, should be more sensible.
