I'm surprised by the multiple c: references, but just add (u) to make
them unique.

    ${(u)${(M)${(fL)"$(mount)"}:#[a-z]:*}%%:*}

Ah, as I said, tweaking.  Need a couple of "preserve array-ness"
operations because of the outer double-quotes:

  "/(${(j:|:)${(@u)${(@M)${(fL)"$(mount)"}:#[a-z]:*}%%:*}})/"

But you're right, since every drive is just a single letter you can do
it with a character class instead of with alternation.  I couldn't do
that because I was testing with (lib|tmp|usr).

  "/[${(j::)${(@u)${(@M)${(fL)"$(mount)"}:#[a-z]:*}%%:*}}]/"

However, I think even that is overkill -- there isn't anything that
matches the pattern /?/ yet is not a drive letter, is there?  So just

  if [[ $PREFIX != /*/*/* ]] && compset -P /?/

should set $IPREFIX to the drive path.

Hm, I'd like to see ^X? (completion debugging) output for that,
because it might be related to the attempt to match
case-insensitively.
