If you build it on a little-endian machine, it should run
on a big-endian machine (IL is designed to be portable).

However, if you inadvertantly introduce a system dependency,
such as fread'ing a structure without performing manual
byte swaps, then the behaviour will be inconsistent on the
two machines.

Using fread on structures is never a good idea, even when
compiling on native systems using gcc.

The cscc compiler outputs portable binaries, but it is still
necessary for the programmer to follow good portable coding
practices.

We can certainly document some of the common pitfalls, and
ways to avoid them.
