Please post more complete sources.  You need something like this:

with System;

package Lua_H is

   type lua_State is private;

   function luaL_newState return lua_State;

private

   type lua_State is new System.Address;

   pragma Import (C, luaL_newState, "luaL_newState");
end;

with Lua_H;

procedure Test is
   L : Lua_H.lua_State;
begin
   L := Lua_H.luaL_newState;
end Test;

(Later, you should probably drop the prefixes and move the luaL
functions to a separate package.)
