This will get me the correct path to link to, but I still think it's
unnecessarily ugly (and took a while to cover all the possibilities of
not-so-well-formed cygdrive prefixes):

--8<---------------cut here---------------start------------->8---
CYGDRIVE="$(/usr/bin/cygpath -u C:)"
WINETC="$(/usr/bin/cygpath -S -u)/drivers/etc"
WINETC="/proc/cygdrive/${WINETC#${CYGDRIVE%c}}"
--8<---------------cut here---------------end--------------->8---

versus the hypothetical

--8<---------------cut here---------------start------------->8---
WINETC="$(/usr/bin/cygpath -S -U)/drivers/etc"
--8<---------------cut here---------------end--------------->8---

BTW, the path comprising the cygdrive prefix probably needs to be
sanitized to avoid things like

--8<---------------cut here---------------start------------->8---
$ mount -c /bla//fasel////blum//////
--8<---------------cut here---------------end--------------->8---

leaking into the wild.


Regards,
Achim.
