xterm: fatal pty error 23 (errno=22) on tty /dev/pts/x

[Hugh Daschbach]

After upgrading to Yellow Dog Linux 2.2 xterm fails with the error
message:

    xterm: fatal pty error 23 (errno=22) on tty /dev/pts/x

The failure seems to stem from a change to
/usr/X11R6/lib/X11/app-defaults/XTerm.  The line:

    *VT100*eightBitInput: false

is preceded with a reference to bugzilla bug #49315.

To workaround this issue I placed:

    *VT100*eightBitInput: true

in my .Xdefaults file.  Would be interesting to know why /dev/pts
support on ppc seems to cause this failure.
