actually, found the real real problem.

our pre-processor is writing the error messages to stdout
instead of stderr, so the followon grep isn't finding the messages.

i've gotten our compiler people working on it now.

thanks again for everyone's help.

thank you, i figured out the problem based on your note.
i was looking in the wrong area (stupid, i know).

our pre-processor is giving a 0 exit status with this warning,
instead of non-zero.

thanks for the help.  i think my brain went on vacation a few days

i've looked at that section of the code, and i can't figure out what
the heck it's trying to do.

It's trying to find a C preprocessor that works correctly.  On your
system, "cc -E" appears to run the preprocessor, but it does not work as
expected.  In particular, preprocessing the file:

    #line 2778 "configure"
    #include "confdefs.h"
    #include <ac_nonexistent.h>

completes successfully with no error messages whereas it should have
failed and produced an error message about not being able to find
ac_nonexistent.h.  You may want to try running it by hand to see what's
going on (you can stick an "exit" in the configure script at this point
to save conftest.c [the above file] and confdefs.h if you want, but
there shouldn't be anything interesting in confdefs.h at this point). Is it possible that you actually have an ac_nonexistent.h header
somewhere that its finding?  If so, get rid of it!
