This no longer works is 5.2 because in 5.1 luaL_register called
(the undocumented and badly named) luaL_findtable which did that magic,
but 5.2 lacks luaL_findtable.

If you want to keep this way of registering your libraries is 5.2,
but don't want to use or require LUA_COMPAT_MODULE when build Lua,
you can copy luaL_findtable from the 5.2 source and use this version
of luaL_register:

void luaL_register(lua_State *L, const char *libname, const luaL_Reg *l) {
  lua_pushglobaltable(L);
  luaL_findtable(L,-1,libname,0);
  luaL_setfuncs(L,l,0);
}
