The reference platform never lies. Better figure out how to break your
machine instead :)

It should be easy to fix, since you have a real 64-bit machine. Sorry
I've lost access to my DUnix-4.0 boxes so can't help directly. Look at
what configure decided your int8 setup should be.

Both are solved with platform-specific "expected" results (as would the
exp "failure" earlier, though it should be fixed on the reference
platform).

This has always been due to conflicts between the two styles of
date/time support on Unix boxes. Perhaps it isn't being configured
correctly?
