I can't even remember how to compile!

My previous programs which don't require linking to a NAG library seem to compile thus:

gfortran -m32 program.f90 -o program

If they do require linkage, I compile like this:

gfortran -m32 program.f90 /opt/NAG/fll3a21dfl/lib/libnag_nag.a -o program

Silly me. Won't forget that now, will I?
