From xinit.sh:
/usr/bin/mkshortcut $CYGWINFORALL -P .....
where $CYGWINFORALL is probably -A
This is the same bug as this one:
http://www.cygwin.com/ml/cygwin/2013-01/msg00261.html
I never replied directly to that message (I was still AWOL at the time),
but I later referenced it here:

...and that's still true. Is there are way for setup.exe to delegate
its elevated credentials down to /bin/bash, and thence to
mkshortcut.exe? Otherwise, even the *fix* for this bug will just make it
not hang or crash; it will still fail to modify the all-users start
menu/desktop.
Do we need to extend setup.exe *itself* to accept instructions from
packages somehow (maybe in the setup.ini?) so that setup.exe *itself*
can do some of these privilege-requiring tasks?
