Which port are you using?

Sounds like it has a wrong definition for portPOINTERSIZETYPE

Yes - or no definition at all. Only newer ports have the definition. The older 16-bit ports, which have different sizes as per the warning, and don't have the definition, can generate this warning. The warning can be ignored, or you can add portPOINTERSIZETYPE to your portmacro.h file.
