Mike,

Once again I have to apologize for the tardiness of this reply.

>Thanks for getting back to me. Attached is the configure log.

I just checked through the online netCDF support archives:

http://www.unidata.ucar.edu/glimpsedocs/ghnetcdf.html

and found (using g++ as the search key) the following snippit from
another user about using g++ 3.5.1:

Russ Rew commented:

Good question.  It's unfortunately generated automatically by the old
version of autoconf we used to generate the configure script from a
"configure.in" file.  Before releasing this version, I would like to
update it to use the current autoconf/automake/libtool packages, so we
don't have problems like this.


So, it looks like you were correct in your comment that 'configure'
should be modified to correctly test g++ 3.2.2.  Until we do that, you
will need to do the same sort of thing that Hein Zelle did:
comment out the line "extern "C" void exit(int);"

Hi Tom

Thanks for the feedback.
