Ugh, top-posting...  Reformatted.

As Eric said, using -xdev should do it at the cost of not recursing into
the drive roots (it'll have the same effect as removing the real /cygdrive
directory had in earlier Cygwin versions, which, of course, was not
possible with your setup).

BTW, you ought to get the same warning on Linux if you have weird mount
structure, e.g.,

/local/users/test on /u/test type none (rw,bind)
/local/users on /u/test/users type none (rw,bind)

(I don't know if the Linux "mount" will allow creating such loops,
though).
HTH,
	Igor
