OK. Good.

Actually, I think the PREC setting should apply only to floating-point
operations, but this is an integer calculation. So I don't think PREC
should matter.

Ha.

Here's another crazy idea. Can you please patching extension/Makefile.am
as attached, and then rebuilding with "make clean && make && make check"
and see if that fixes the problem? I'm starting to think that it's a dynamic
linking issue and that somehow MacOS is using a separate copy of the mpfr and
gmp shared libraries for the extension that have not been initialized by the
main gawk program.

Thanks,
