The problem is that you can't pick and choose.  If you're doing a top-level
make from devo stuff is going to go to where you've set your prefix and
exec-prefix.

FWIW, I like Mumit's proposal.  I think it is perfect.  I hadn't considered
/lib == /usr/lib but I think that that is a good idea, too.

Mumit also suggested in private email that "cygcheck" do a little
rooting around in the directory structure to report how things were laid
out just in case an adverturous user decides to remove the /usr/bin
symbolic link.
