20040709: ldm-mcidas compile problem

Hi Mark,

Instead of trying to troubleshoot your build on Slackware -- an OS we
do not have in-house --, why not try using the binary ldm-mcidas
distribution I have provided for RedHat 8.  I believe that it will work
with no problems for you:

machine:   ftp.unidata.ucar.edu
directory: pub/binary/linux8_2.4-i686
file:      ldm-mcidas-2003.tar.Z

Please let me know if this does not work for you.

Cheers,

Tom
