The lua_isinteger function is only present in Lua 5.3+. To maintain compatibility with earlier Lua versions (notably 5.2 and 5.1) this pull request gates the usage of this function with defined pre-processor checks. In the case where the symbol is not defined, we unconditionally fall back to existing logic that treats the maybe-an-int item in question as if lua_isinteger returned false.
