Hi,

I found some time to look into this. When the frame was maximized and the
tool-bar was disabled, the function x_set_window_size was never called.

The following patch makes the frame exit the fullheight or maximized states
when the tool-bar is disabled, which makes the call x_set_window_size
reappear. It does NOT, however, return the frame to the fullheight or
maximized states when the toolbar is re-enabled (I don't even know if it
should). In addition, it does not support frame-inhibit-implied-resize
either (which would require a lot more work).

I read in the emacs-devel group that there is a feature-freeze in place --
does this mean that I shouldn't commit this?

Also, the current Emacs master branch doesn't build on OS X 10.6.8 after an
attempt to David Reitter to eliminate warnings -- I think it's an easy fix
(David don't have access to a 10.6.8 machine but fortunately I do).
