Sorry Dan,

I only know two ways to compile on AIX machines, and they can be found
here:

http://my.unidata.ucar.edu/content/software/netcdf/builds/index.html

In terms of changing the size of various types, well, I really don't
know how or if that will work with netCDF. I suggest you ask on the
netcdf mailing list to see if anyone else has tried it.

If you don't want the C++ interface, set CXX to '' before configuring,
and that will turn it off.

Good luck!

Ed
