[RegCNET] Bug in RegCM 4.1 configure

[Martin Scarcia]

Hello everybody,

during our current ICTP activity we discovered a small bug in the
configure script of the official RegCM 4.1 package. The CLM option can
now be compiled also with GNU Gfortran, but the configure script will
not allow you to do so. To avoid this configure the model with
Gfortran as usual, but do not activate the CLM option. Once finished,
edit the Makefile.inc and replace the line

USECLM = 0

with

USECLM = 1

Finally, run the usual compilation steps (e.g. make all).

Thanks for your patience and understanding :)
