No thanks...I don't want to go down that road. (1) We don't have a
mechanism for releasing binaries of for updating them after bugfixes.
(2) I don't know how to have a "universal" MPI code linked in, and
having something that doesn't match the hardware is likely to impact
performance far more than compiler options. (3) We would need to purchase
"commercial" compiler licenses. (4) If you look at the number of options
in Bob's config_data directory, you can see that some very large number of
executables would be required.

On another subject: Can you folks look at the pg_pgb test case? I get the
same result on two different platforms, but both disagree with the save
