This has been on my mind, actually, for a while now.  (Note that, with
the possible exception of cygports, it will not make any difference to
me.  So these are suggestions, not requests.)

It would seem that when setup encounters the error that Garret
encountered, it should ask whether to continue anyway (i.e., invoke -X)
or abort.  If nothing else, it will avoid some of emails to the list
that repeats Garret's report.

It would also seem that a checkbox that invokes the -X functionality
would offer flexibility to people who know in advance that there is no
sig but do not remember the option don't need to use -X often enough to
have a shortcut, etc.

Related #1:  -X (and -K, -S, -u, and -U?) might be added to FAQ entry
on setup command-line usage:
http://cygwin.com/faq/faq-nochunks.html#faq.setup.cli.  A link to
http://www.cygwin.com/ml/cygwin-announce/2008-08/msg00001.html might be
appropriate.

Related #2:  It would be useful to update the setup command-line usage
link on http://sourceware.org/cygwin-apps/setup.htm to perhaps point to
the FAQ entry.

And thanks for all the work that's gone into setup.
