Well, here f90 I mean FORTRAN 90 (or 95) compiler,

Yes, on Linux the present RegCM3 version only supports Portland FORTRAN
compiler (pgf90) and Intel FORTRAN compiler (IFC) and we just provide
the corresponding netCDF libraries of them.

The version doesn't work with g77, even though you can add netCDF
library, but it is not enough, g77 cannot read big-endian binary
datasets (like SOILCAT.05, AEROSOL.dat, GISST_194712_200209, etc.),
And g77 might have problem for some sentences we used in codes.

By the way, it's the historical reason that most of Atmospheric
Models only support big-endian binary data (RegCM, MM5, and even
WRF). In future, it's possible to remove this dependence, if we
only are allowed to have netCDF files as input/output.
