Subject: [PATCH v2 2/2] Cygwin: expose all windows volume mount points.

Realized an oversight (besides the messed-up subject!) after sending:

should have something like
+  if (_my_tls.locals.drivemappings)
+    {
+      delete _my_tls.locals.drivemappings;
+      _my_tls.locals.drivemappings = NULL;
+    }
