"May".  I recall a patch to setup to add an "--install-all" option, but I
don't think it's been applied.  Here's a reference to the thread:
<http://cygwin.com/ml/cygwin-apps/2005-05/msg00235.html> -- feel free to
extend on it to get a "--reinstall-all" option (which would probably be
more useful anyway).

Once the above option is in setup, this might work.

Careful there!  One issue with this is that unless you're running a
non-Cygwin sshd and bash, replacing the dependencies of either program
will require a reboot.  Another issue is that setup.exe is a pure Win32
program, and will require that the sshd service has the "interact with
desktop" bit.

They contain the listings of all installed packages -- "cygcheck -l" uses
them, as well as "cygcheck -f".
