I'm kind of thinking the same.  Why not let the PIC setting code just do
its work and afterwards check a cache variable for a possible override?
That wouldn't require reorganizing the code at all.

A reorganization could be useful for other, independent reason (such as
factorizing the code for reuse by the lib-link module, for example), but
for now, I don't see that this is necessary.

Thanks,
Ralf (who'd probably only get to it after the holidays)
