OK, these should work fine in building v2002.

This step is needed.  The settings are used in the netCDF, HDF,
and Tcl/Tk portions of the build.

Right.

Sounds good.

The main McIDAS portion of the build figures out what it needs in the
build based on content in the 'mccomp' script (which gets made from the
mccomp.sh script in the distribution).  The netCDF, HDF, and Tcl/Tk
portions of the build use the configure approach that is common to
a large portion of Unix packages.  They all try to figure out what
compiler to use and what flags to use for those compilers.  Evidently,
and this is what I have been finding with the HDF portion of the build,
the HDF section's configure is not as "smart" as the netCDF or Tcl/Tk
portions.  In any case, if the environment variables like CC are set,
_all_ of the sections will use the settings in their builds.  So,
setting the variables makes the build environment predictable.

>Thanks

Please let me know how the build goes after you do the 'make clobber'
and set the environment variables.
