How to enable long long integer support?

["Alex Chen" <alex.chenhl@...>]

Is it possible to config lua to express Integer in 0~0xffffffffffffffff, and can exchange the long long integer between lua and c++?

I tried to modified luaconfig.h with

#define LUA_INTEGER long long

but it not work.

I use luaL_checkinteger and lua_pushinteger to exchange the value.
