Will do, but could you include the details of the announcement in the emacs
source distribution somewhere, as is done for the other variants with specific
instructions? I'm only incidentally building it in a cygwin environment - it
didn't even occur to me to check the general cygwin mailing list.

Lynn,
Rereading your earlier message about problems during package installation, I
see
I didn't really respond to that. But it has nothing to do with the present
bug,
so please make a fresh bug report and give full details. And please follow
the
instructions in the announcement I cited. If you're working in your own
build
of Cygwin emacs that you haven't installed, you might also have to add its
native-lisp directory to
/var/lib/rebase/userpath.d/<username>
I am doing exactly what you surmised, running a build I haven't installed - in
fact that I built with --prefix=/does/not/exist/ to ensure system installed
site-lisp files will not get injected into the load-path while doing do. So
I'll try that first. Although I think the packages generating the fork failures
should be going into the cache in my home directory.
