Should be fixed in revision 110822 on the trunk.  Please test, as I
don't have dead keys on my keyboard to test them myself.

(I didn't commit this on the release branch, because this problem
existed since about forever, and so doesn't fit the criteria for
changes on the branch as set by Chong.)

That you cannot do this in Emacs is by design: when
w32-scroll-lock-modifier is nil, pressing that key when Emacs has
focus is handled as a function key, and Emacs forcibly restores the
previous state of Scroll Lock when you release the key.
