Description:
------------
bcompiler is in most cases used to hide the php code. This is working perfectly.

The only thing I don't like today, is that it doesn't handle endians the same way on different platforms.

Problem: If I compile a php file on a Intel processor, it wont work on Sparc processor (since sparc expect the file to be in big-endian format).

Workaround is to have to set of php files. One for Intel, and one for Sparc.

What I would prefer: The bcompiler sees that the processor is a big-endian processor, it would then convert the bytecode to big-endian style if it sess that the php file is compiled in a little-endinan format.

Os is irrelevant..

Could you suggest some defines that can tell if the system is big-endian (like __x86_64__ that is used to tell of 64-bit)?

I'll probably make bcompiler to always read/write it in little-endian format as of 1.0. But I care about 32-bit vs 64-bit more, which is no so easy to solve...
