broken menu items

[Lennart Staflin]

In GNU Emacs 21.3.50.7 (powerpc-apple-darwin6.6)
 of 2003-09-11 on Saturn.local.
configured using `configure '--enable-carbon-app' 'CC=cc 
-traditional-cpp' 'CFLAGS=-g' 'CPPFLAGS=-traditional-cpp''

Some of the entries in menu bar of the Carbon port of Emacs
seems to do nothing. Like the "Edit > Select All".

I had a closer look at this and it seems that it is a call to 
SetMenuItemRefCon in add_menu_item that is misplaced, it is called even 
for separators, but for these a parameter is not set but has the same 
value as for the preceding item (hmm. it is actually uninitialized, 
must be reusing the same stack position). This clobbers the preceding 
item.

Moving the call to SetMenuItemRefCon seems to fix this.

        * macmenu.c (add_menu_item): Don't call SetMenuItemRefCon for
        separators, as the pos parameter will be incorrect.
