New issue 319: Cannot link stdio `getline` with Apple GCC

Description:
  In the new fortran_reader.pyx, we import the getline function from stdio.h. This works great on any sane linux system, but does not work for Macs. This code works fine on NERSC machines, but I tried updating and running locally, and got this trace:

{{{

I looked into this more, and found that Apple's stdio.h (from FreeBSD, not GNU) does not contain getline. God knows why. Source: http://forums.macrumors.com/showthread.php?t=891660

I'm not sure what the best fix is, but I know a lot of yt users use the Apple shipped gcc, so we should probably fix this. We can grab the GNU getline source, as someone suggests above or we could use another function. Anyone?
