Dr. Neinhues:

I believe I have sorted out the problems in the netCDF configure relating to 
fortran flags.

The only flags that should matter now are FFLAGS (for F77 flags) and FCFLAGS 
(for F90 flags).

The 64-bit build capability has been taken out of configure. It was too much 
for use to be able to support.

If you want to try our latest version and see if it works better for you, get 
the snapshot distribution:

Thanks!

Ed
