It looks exactly like the sort of platform-dependent rounding issue that
Bruce and Michael Glaesemann spent a lot of time on recently. It might
be interesting to see if CVS HEAD works any better under these
conditions ... but if it doesn't, that doesn't mean I'll be interested
in fixing it. Getting the float datetime code to work is hard enough
without having a compiler that thinks it can take shortcuts.
