Even on a little endian machine (Alpha) defining LITTLE_ENDIAN broke things
for me!

I haven't got around to debugging this yet. Also the optimiser on cc breaks
the union hack in DoBranch(). I'm unsure if this is an optimiser problem, or a
code problem. Does anyone know just how portable signed to unsigned conversion
by use of a union is?

With LITTLE_ENDIAN undefined, and optimisation turned off, I've now got xbeeb
working on the Alpha, but with some odd caps lock problems. (I'm not even sure
how to generate caps lock on this shrunken keyboard - all the obvious key
combinations no longer work since I upgraded the OS.)

Also, the palette swapping seems somewhat random - sometimes no new colourmap
is allocated at all.

It's looking promising otherwise though.
