             * broken.  Versions of xkbcomp below 1.2.2 had a bug where they
             * would interpret a symbol that couldn't be found in an interpret
             * as Any.  So, an XF86LogWindowTree+AnyOfOrNone(All) interp that
             * triggered the PrWins action would make every key without an
             * action trigger PrWins if libX11 didn't yet know about the
             * XF86LogWindowTree keysym.  None too useful.
             *
             * We only do this for XFree86 actions, as the current XKB
             * dataset relies on Any+AnyOfOrNone(All) -> SetMods for Ctrl in
             * particular.
