If you `make install' twice then the second time the directories aren't
created anymore, so the `make uninstall' would not attempt to remove them.
Not good.

That's not quite it either. If I install something into
/opt/foo-0.99/{bin,lib,include} and then it only removes the bin, lib, and
include parts, then it's arguably being less than helpful.
> d) remove all the levels that are empty
That would certainly be the easiest. Perhaps once could make provisions
that certain "standard" directories (e.g., /usr/local) shouldn't be
removed, although I don't see a reason for keeping them around. It was
objected that other, badly packaged software might blindly assume that
some standard directory exists, but how hard is it to `mkdir /usr/local'
if you get `/usr/local: no such file or directory'?
The added beauty of this approach would be that `rminstalldirs' would be
to `rmdir -p' what `mkinstalldirs' is now to `mkdir -p'. A possible
(though perhaps not perfect) implementation of rminstalldirs is attached
for your perusal.
