Don't worry, we have the same objectives.  I totally agree that local
#defines are a bad thing, which is why I proposed this project in the
first place.

I'm just saying that this is a "first-patch" sort of learning project
and I think it'll avoid some list spamming and discouragement if we
can figure out the scope and shake out some of the teething problems
ahead of time.  I don't want to end up with multiple versions of
dozens of little 2-3 patch series posted every week or two.  I'd
rather be able to deal with a whole block of them at one time.

Do you have any pointers for the best way to do this?  Is it as simple
as comparing output of "objdump -d"?

Thanks for the additional tips.
