I just tried the invoking the command

   /bin/CC -c -g -woff 1110,1167 -I../libsrc -DNDEBUG netcdf.cc

in the netcdf src/cxx directory on an IRIX Release 6.2 IP26, and it
worked with no problem.  It also worked on an IRIX 5.3 system, though in
that case it issued a warning about "integer conversion resulted in a
change of sign".  We don't have an IRIX 6.0 system on which to try this,
so we can't reproduce the error.

Is it possible it's just a configuration problem with your C++ compiler?
For example, are you able to compile and run a simple C++ program such
as the following 4-liner?

#include <iostream.h>
int main()
{
    cout << "hello, world\n";
}

I don't know why /bin/CC would think netcdf.cc (a C++ source file) is an
object file.  Maybe that version of /bin/CC requires a different file
extension than .cc?

A possible workaround, if you don't need the C++ interface, is to just
build it again after specifying you don't have a C++ compiler, setting
the CXX environment variable to "" before removing config.cache,
rerunning the configure script, and running "make clean all test" again.
