Lua 5.2 Truncation error in lua_tointeger

[liam mail <liam.list@...>]

When using the ieee754 trick on an x86_64 machine where
sizeof(lua_Integer) ==8 and sizeof(int) == 4, the following fails in
5.2 yet passes in 5.1

		CPPUNIT_ASSERT(sizeof(lua_Integer) == 8);
		CPPUNIT_ASSERT(sizeof(int) == 4);
		lua_Integer input = 0x1ffffffff;
		lua_pushinteger(l, input );
		CPPUNIT_ASSERT_EQUAL(input,lua_tointeger(l,1));


This is due to lua_number2integer when LUA_IEEE754TRICK is defined and
called by lua_tointegerx
#define lua_number2integer(i,n)		lua_number2int32(i, n, lua_Integer)
