bug#4022: 23.1; 'cd' and 'pwd' not working

[Pranith Kumar]

'cd' and 'pwd' are not working in gdb under emacs. Am using emacs 23.1 on RHEL 
4 WS.

Here is a brief description of what happens:

(gdb) cd /home/bob/
_
The cursor just hangs in the next line when I press enter.
If I press tab for tab completion, emacs just hangs.
