this option changes it to the M32RX.

 warn explicit parallel conflicts or  Wp

Produce warning messages when questionable parallel constructs are encountered.

 no warn explicit parallel conflicts or  Wnp

Do not produce warning messages when questionable parallel constructs are encountered.

The following options are available when as is configured for the Motorola 68000 series.
