Problems with emacs shell starting with 2011-05-05 snapshot

[Ken Brown]

Starting with the 2011-05-05 snapshot, I can't start a shell under emacs.  Here are the steps to reproduce:

1. Start emacs in a mintty window.
2. Type <Alt-x>shell<enter>

This yields the following error message in the shell buffer:

  sh: cannot set terminal process group (-1): Inappropriate ioctl for device
  sh: no job control in this shell

Starting with the 2011-05-28 snapshot, the error message changes to

  Process shell aborted

Starting with the 2011-06-01 snapshot, it changes again, this time to

  Process shell stopped (tty input)

I still get that error message with the 2011-06-14 snapshot.

My system is Win7 SP1 64-bit.  I also have an XP system that I can test this on later.  I haven't had a chance yet to dig into the emacs code and see if I can boil this down to a Simple Test Case.
