One of the nice things about higher-level languages such as C (when

about pointer size differences in many cases unless they start using
VMS-specific APIs.

Of course, that all changes if you are porting crappy software that
tries to stuff addresses into integers or if you are doing device
driver/hardware work where things like bounce buffers may come into play.

 Of course, that is what ABIs are _supposed_ to be for...

Yes.
But that is the point.
The ABI is right by definition. The compilers pointer size is
just usually right.
