Found it.  The method to compute the mount flags from the options
given to the mount(1) command have been changed and accidentally the
default is 0, instead of MOUNT_BINARY.  Fixed in CVS.   For the time
being, the workaround is to set the mount option explicitely:

  mount -o binary,... -c /

or, which is much less error-prone in the long run, to create a cygdrive
mount in /etc/fstab.

Since it's auto-generated, you must have deleted it.

That's what a User's Guide is for:
