Keir, it would not be easy to modify the files that I'm adding.
Instead, I modify the Lua interpreter so that it no longer performs
floating point operations, but is otherwise a standard ANSI C program.
The Lua interpreter and Mini-OS are compiled and linked using a
cross-compiler combined with newlib for C library support.  Making
extensive modifications to both newlib and the Lua interpreter is
unappealing, to say the least.

Don't you get horrible namespace collisions when linking with a C library replacement? Not just stddef.h, but what about the definitions in minios's include/lib.h?
