I just tried building netcdf-2.4 on an IRIX 5.3 MIPS 4000 (Indigo Elan)
using

   ./configure; make all test

with no changes to the default CUSTOMIZE file, and it seemed to work fine,
including the C++ interface build and test (the default value of CFLAGS is
`-O', so it's not necessary to specify that explicitly).

Then I added the "-mips2" flag to try to reproduce the symptoms you are
seeing (with sh or ksh, I put this in the environment by just preceding
the command with the environment variable setting for that command
invocation):

   make clean
   CFLAGS="-mips2 -O" ./configure
   make all test

This worked fine, although only the C sources were compiled with the -mips2
option; the Fortran and C++ sources would have needed me to set FFLAGS and
CXXFLAGS environment variables as well.

Then I tried setting the CFLAGS environment variable to "- -O -mips2" to use
exactly what you said you tried, though I don't know what the "-" flag is
for:

   make clean
   CFLAGS="- -mips2 -O" ./configure

This didn't even make it through the "configure" script, so it looks like
"-" is not an acceptable option to the SGI C compiler.

Here's the details of the system I tried this on, which looks like it has an
even older version of the C++ compiler than you have:

Since I can't reproduce the problem, I'm afraid I have no suggestion except
maybe to tell configure that you don't want the C++ interface by setting the
CXX macro to the empty string.
