//a has always been available in cygwin.  Although its use is
deprecated, it has never been removed and it has nothing to do with
/cygdrive.

I'm not advocating that people set their /cygdrive to / and I will be
changing the example that mentions this.  However you seem to be fooled
by something that you haven't even tried.  Hopefully not too many other
people will imagine problems and refuse to empirically test them.

I characterize these kind of discussions as the "I wonder if it is
raining outside" variety.  Rather than wonder, stick your hand out of
the window and test for yourself.

Rather than speculate on what you think may be wrong, test the snapshot
and report on problems.
