20000107: gempak and long filenames

Chris,
You may be able to work around the problem by letting the substitution
occur within Gempak, rather than in the csh script, eg:

gdfile = \$NGMFILE+\$ETAFILE+\$AVNFILE

The really cheesy way to do it would to temporarily create a link
to each file to /tmp/ngm, /tmp/eta and /tmp/avn and use those
as the filenames.
