The above message contained the following:

To explain to others who might read this, the error reported in the 
file "configur3.log":

    checking C++ compiler "/gad_opt/SUNWspro/bin/CC"... configure: warning: 
/gad_opt/SUNWspro/bin/CC failed on standard C++ test program
    configure: warning: Could not find working C++ compiler
    configure: warning: Setting CXX to the empty string
    configure: warning: The C++ interface will not be built

is explained in the file "config3.log":

    configure:1225: checking C++ compiler "/gad_opt/SUNWspro/bin/CC"
    configure:1243: /gad_opt/SUNWspro/bin/CC -o conftest  -DNDEBUG  conftest.C

                                    #include <iostream>
                                    int main() {
                                        std::cout << "";
                                        return 0;
                                    }

Your C++ compiler should have been able to build this test program.  The 
failure indicates a prblem with the C++ installation.

It looks like you have subdirectories under "/gad_opt/SUNWspro/" that
contain version-specific compiler installations.  It is possible that 
the "/gad_opt/SUNWspro/bin/CC" compiler is actually a link to a version-
specific compiler in another subdirectory and that that installation
isn't quite complete.

Can you ask advice from a system administrator on this problem.  You might
be able to experiment with the compiler installations (copying libraries,
creating symbolic links, etc.) using the above test program until it works.

Those values would not be changed because the configure script executes in
a child process and a child process can't affect the environment variables
of its parent process.

Well,  you know have C and Fortran versions of the netCDF library.  Do you
need the C++ version?

I understand completely.
