as a means of adapting the following Lua 5.2 code for use
with Lua 5.1:

LUAMOD_API int luaopen_bit32 (lua_State *L) {
  luaL_newlib(L, bitlib);
  return 1;
}

My question is, why:

#define LUAMOD_API

instead of:

#define LUAMOD_API LUALIB_API

?  I have some vague notion that Windows users need the proper
__declspec(...) on their shared-library luaopen_*() functions.
