My point is to realize that most USE_* variables change signature globally.
USE_YP even changes libc signature.

Clarified, maybe yes.  But very incomplete.

Me too.

We should audit all those use and make them modular == no signature change
but be "subsets".

I was confused because those are "almost done", but not finished.  Most
opinions I've got from people is "why do you do that"?  No one has answered
my question - why don't we distribute binary patches?
