You have to be stopped in the debugger in order for the commands you
type in the console to be sent to gdb. Other than that, I don't know
what could be going wrong. The first step in debugging this is to do:
1) Quit Xcode.
2) In Terminal, say:
$ defaults write com.apple.Xcode PBXGDBDebuggerLogToFile YES
$ defaults write com.apple.Xcode PBXGDBDebuggerLogFileName
/tmp/IncludeInBug.log
3) Restart Xcode, and run the debugger and try to send some commands
from the console. Make sure the program you
are debugging is stopped at a breakpoint (or you have interrupted
it.)
4) If it still doesn't work, file a bug and attach
/tmp/IncludeInBug.log to the Radar. I can at least tell if
any of the commands are making their way to gdb, and if so, why you
aren't seeing the results.

There isn't a GUI way to do this yet. But you can do it in the gdb
console. Just bring up the Debugger log (under the Debug menu), and
use the "watch" command.
One little subtlety, if you do something like:
(gdb) watch foo->bar->baz
I'm obviously missing something important here, but I've never been
able to type commands into the debugger console. The text goes in, but
gdb never executes any commands. You just end up with "(gdb)" followed
by your command and a load of blank lines where you've been pressing
Enter trying to get it to do something.
