I am trying to bring up gnuemacs 18.54 on an HP9000/350 under HPUX
6.5.  We are experiencing a problem with the suspend functionality;
typing the suspend character suspends emacs with a garbled screen, and
bringing emacs back to the foreground causes it to hang.
Interestingly enough, using M-X suspend-emacs works perfectly (it
suspends very nicely, and runs correctly when restarted.  It IS doing
a suspend, NOT just spawning a subshell as it did under earlier hpux
releases).

It seems like emacs needs to turn off the suspend character somehow so
it can trap it itself; does anyone out there know how to make it work
(some magic ioctl, possibly?)  Any help would be appreciated.  (please
respond by mail; I will post a summary of fixes later).
