Zsh stopped completing mixed paths with update to 4.3.9

[Hudec, Jan]

Hello,
 
Since today's update, zsh completion no longer recognizes mixed-style paths, ie. c:/something instead of /cygdrive/c/something -- that worked until now and was extremely useful, since all native programs I need except cmd.exe and all cygwin ones except midnight commander (and I don't use that) understand them the same. Is there some configuration change that needs to be done to get it working again or something? I didn't see anything in the changelog (/usr/share/doc/Cygwin/zsh-4.3.9.README).
