[RegCNET] Lateral Boundary Treatment (fwd)

[Richard Anyah]

I am getting this error while compiling RegCM3 using ifort compiler on
(64-bit)Linux redhat 5.0 Enterprise.

ld: skipping incompatible ../../Commons/env/liblinux64//libnetcdf.a when
searching for -lnetcdf

I hope somebody has come across the same problem before and can advice how
to resolve it.

Richard
