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!
