GDB: Don't display I/O buffer window.

[chandan r]

Hi all,

Quoting from the Emacs manual,
"However, if `gdb-use-separate-io-buffer' is `nil', the I/O buffer
does not appear and the primary source buffer occupies the full width
of the frame."

Emacs displays the 'I/O buffer', Inspite of setting gdb-use-separate-io-buffer
to nil in my init file. Please let me know what else I need to add in my init
file to disable the 'I/O buffer'.

Regards,
