Or if FORTRAN 77 appeals to you because of its simplicity, you
might try writing F77 code but using the "free-form" syntax of 
"modern" Fortran (Fortran 90 and beyond) and compiling with the
"-ffree-form" option.  I tried this with your version of Geoff's
example, and while the f77 on my Linux system complained about
the "c" comments, once I changed "c" to "!" the code compiled okay.

Just sayin', maybe, since I'm not really optimistic that you'll
get on any better with any version of Fortran than you've done
with C.  But there's something to be said for persisting in the
face of adversity, maybe.
