The main question is: *why* would one want to programmatically find out
the cygdrive prefix?

If all you want is access '/cygdrive/c' via a POSIX path, wouldn't
"cygpath -u c:" do the right thing?  In fact, barring special mounts,
"cygpath -u c:|sed 's#/c$##'" should do what the OP asked.

Alternatively, one could actually use the quotes that "mount -m" produces,
via something like

mount -m | grep -- --change-cygdrive-prefix | \
  xargs bash -c 'while [ $# != 1 ]; do shift; done; echo "$@"' --

HTH,
