[osx] edit/paste menu item always disabled

[Sébastien Kirche]

Hi,

On the MacOSX build, edit/paste item stays disabled despite of copying 
some text from outside or withing emacs,
or starting Emacs with some text in the clipboard.

At the same moment, edit/Select & paste displays a populated kill ring.

Problem seem to occur only on OSX build (not seen with same cvs 
checkout on GNU/Linux).
Version : Gnu Emacs 21.3.50.1 (powerpc-apple-darwin7.5.0) of 2004-09-07
