arbitrary precision gfortran

[Yigal Weinstein <yigal.weinstein@gmail.com>]

Is there a simple way of implementing arbitary precision in gnu fortran
compilation?  I got rather confused about what could be easily
done and what cannot be easily done researching it myself.  So any
feedback would be great.

The code I am working on is primarily f77 and it would be better to keep it fortran than translate it to C etc..
