19991203: Compiling GPRCM for Solaris x86 using gcc/f2c

Tim,
You should be able to build the current distribution under X86 
using gcc and fort77, since these compilers are the combination 
that I use on Linux. I will be using g77 rather than f2c 
for the next major release of Gempak however so that we can
avoid these headaches of double underscores in subroutine names.
When I originally ported GEMPAK to the intel platforms, g77 did not 
support several features needed by the source code- but f2c allowed
these features.

So, my suggestion would be to install g77 with gcc in the furture
if you don't already install that part of egcs.
