That is a good point. :-)
The default for Coldfire target should be .l

Remember that AHCC is a Pure C replacement.
If I change the default to .l for Coldfire, the register might still
hold only a 16 bit value. (+ rubbish in the most significant 16 bits).

That is when one reassembles PASM code.
Things become different when code is assembled that has never been
assembled by AHCC.

A warning could be usefull with option -7 and no Xm size specified.
(Or check with Digger).

Load the object file in Digger.
Set 'Machine' to Coldfire.
Press d.

That is how I check code produced by AHCC.
