I'm pretty convinced there's something going on (or NOT going on...)
during the upgrade process.  I've seen this report of someone doing a
setup and still having an old cygwin1.dll, it's happened to me (see
thread regarding svn metadata name mangling), and I've had someone
email me about the name mangling issue (who didn't want to post to the
list) discover he had a downlevel version of the cygwin1.dll file

There's also the additional evidence of finding a half dozen or so
files ending in .new /usr/bin and /usr/sbin.  Perhaps Microsoft had a
hotfix or somesuch that might have affected Cygwin when it needs to do
a replace files on boot thing.  I have no idea how that's implemented,
so that's speculation, of course.
