Point taken.  I've put in a large number of hours here, to make Cygwin
installs and configuration for us as smooth as it is, because I want
more Unix-style automation.  (That's just to let you know my position.)

I'm enormously impressed by Cygwin, by what everyone has achieved.
But it isn't all smooth sailing here yet.

It helps a lot being able to ask questions (sometimes silly questions,
sorry), on this mailing list and get good help.  It is appreciated,
thank you all.

Okay, we'll try that first.

True.

Righto.  I'll write a script to check our mirror, independent of
setup.exe.  Then check ours, and pick another mirror site if
mirrors.kernel.org has broken.  (Though I'm not 100% certain that it's
the explanation for my "Subject: Setup problem: incomplete nonexistent
package" thread.)

Cheers,

luke
