Comment 17 for bug 776499

This is also fixed upstream, I think: http://code.google.com/p/vim/source/detail?r=3ecf9e91d88acdb5eaaf93cc15a18914b60e0eb3

    updated for version 7.3.315
    Problem: Opening a window before forking causes problems for GTK.
    Solution: Fork first, create the window in the child and report back to the
                parent process whether it worked. If successful the parent exits,
                if unsuccessful the child exits and the parent continues in the
                terminal. (Tim Starling)

I've built the newest upstream from sources, and I can confirm that the fix works fine: gvim (*without* -f) has a working global menu.
