(Add'l info) Build problem and problem with region in 21.5 under Cygwin.

Here's some additional info. I set debug-on-error to true and got the following
backtrace when I tried to set the mark:

Signaling: (void-variable region)
  zmacs-make-extent-for-region((#<marker at 1 in .emacs 0x1028cd44> . #<marker

  zmacs-activate-region()
  push-mark(nil nil t)

a
t 1 in .emacs 0x1028cd2c>))
  zmacs-activate-region()
  push-mark(nil nil t)
  handle-pre-motion-command()

Can someone familiar with this code help me understand what's going on here?

Thanks,
