worked fine for me with the following set on intel xeon machines (and
i think that on amd as well but i can't check at the moment):

FORTRAN  = g95
OPTS     = -fno-second-underscore -funroll-all-loops -O2
DRVOPTS  = $(OPTS)
NOOPT    = -ffloat-store -fno-second-underscore
LOADER   = g95
LOADOPTS =

anyway, it is probably nothing too important, but just for the record.

cheers,
