To avoid having to edit much of the original code, I suggest adding the
defines below to your define section at the top:
#define LUAMOD_API
#define LUA_BITLIBNAME "bit32"
#define luaL_newlib(x,y) luaL_register(x,LUA_BITLIBNAME,y)
Also, please preserve the RCS Id line so that we know which version it uses.
lua_pushunsigned can be static.
Perhaps it would be easier to pack all backport code into a lbitlib.h and
just add one line to lbitlib.c, ideally at the very top:
#include "lbitlib.h"
