I've reached the point where I think this is one of those cases where
its better to be fixing things for the common case than catering to
people who have special needs.  If there are people out there who are
populating their /usr/bin area with non-executable files then they
can take special steps to recreate permissions after running setup.

OTOH, one thing that we could do is only turn on executable bits that
exist in the tar archives since those are still available..  We could
have something which does a fixup only on extracted files which are
supposed to be executable.

Don't know.  Maybe someone who is familiar with setup.exe can chime
in.

The emacs thread was pretty long running and there was a lot of churning
about the best way to fix things.  It seems like the solution of choice
for most people is to set CYGWIN=nontsec which is a shame.
