I should make sure the standalone download version of this is up to 
date.  I know the LuaPlus one at 
svn://svn.luaplus.org/LuaPlus/work51/Src/LuaPlus/LuaPlusCD.h is.

The reason for the extra 100k-ish (that's all it was for me) was due to 
the viral effect of linking against an .obj.  All functions in an .obj 
link in, and any other .obj files those functions touch get linked in, too.

The code "LuaState* state = LuaState::Create()" was supposed to create a 
Lua state without linking in any of the standard Lua runtime libraries.  
However, it existed in the same .obj as the function that would 
initialize the standard libraries.  When LuaState::Create() was called, 
all the standard libraries came with it.

This problem was alleviated by moving the function definition for 
initializing the standard libraries into a separate .obj.

The minimal overhead for using LuaPlus now, then, is under 4k.
