Assuming you do find a reliable way to discover the cygdrive prefix, how
do you plan to handle mapped drives for remote shares?  I ask because
you mentioned that you might want to be able to run something like find
on the cygdrive prefix itself, and of course scanning a remote share
like that may not be desirable.  Also, how do you handle the mounted C:
case as well?  Even if you mount it to /c as you have done, I think
/cygdrive/c will also have it.
