Re: Byte-swapping at load time

[Mark Hamburg <mhamburg@...>]

Apple's move to x86 creates a need for compiled scripts that can be
byte-swapped at load time. Admittedly, we've got PPC and x86 code to deal
with, but it would be nice not to share the compiled Lua code.

We've restored the byte-swap logic from 5.1 alpha to our copy of the
sources.
