I haven't seen a popup in Windows Me for some time with the latest
snapshot and I've been able to configure/make cygwin under ME with no
problem.

This should be ok now.

This also should be working now.

I was hoping that Corinna would chime in here but maybe she isn't
following this discussion.  IIRC, I resisted adding the open_fhs checks
to the pty/tty handling early on but eventually was convinced that they
were needed.  Previously, it was pretty hard to have a program with
handles to more than one console but, with the existence of the "new"
windows station stuff it is conceivable, if unlikely that a program
could have two open.  In that context the open_fhs stuff is being
overused, but that was part of the motivation for implementing the new
archetype stuff in the DLL -- then I can eventually get rid of the
open_fhs stuff in favor of setting up console archetypes.  There is
still a lot of genericizing to do to accommodate that but it is a future
goal.
