On Android, char is interpreted as unsigned by default.
When decoding "int 8" format on Android, the following type conversion produces incorrect result:
lua_pushnumber(L,(char)c->p[1]); // (e.g. -39 -> 217)
Changing (char) to (signed char) fixes this on Android and other platforms that treat char as unsigned by default.
