Reverted my ISO C BINDING branch changes.

[Steve Kargl]

Apologies for the code churn. :(.

I reverted revisions 120187, 120190, and 120209, which are a misguided
attempted at cleaning up the ISO C BINDING patch and other inconsistencies
in the source code.

After spending 4 days of looking at the gfortran source code, it 
became painfully apparent that there are a number of atrocious
formatting issues (IMHO).  Some of these problems were carried over
from the initial import of the g95 source code.  Others are probably
due to each submitters personal coding style, which differs from the
GNU coding standard.
