LuaJIT 2 vs. C modules built for Lua

[Alexander Gladysh <agladysh@...>]

Hi, list!

This looks like a silly question, and I feel that it should be
documented somewhere, but anyway:

Can LJ2 be used with C modules, linked with Lua (on Linux / OS X platforms)?

My intuition says "no". Then I feel that LJ2 should ignore LUA_CPATH
and have its own environment variable.

Looks like practice says "yes" — what I've tried worked. But this is
strange. What am I missing? What are the consequences? What if modules
are accidentally compiled as 64-bit code?

Alexander.
