That's weird.  Cygwin always enables the backup and restore privileges
if they are available.  The whoami printout in your previous mail
shows that the privilege is in the token.  But the above code shows
that the AdjustTokenPrivileges() call for the backup and restore
rights both fail with ERROR_NOT_ALL_ASSIGNED.  The problem is that
there's no indication why it fails.  Per MSDN this should only happen
if the privilege is not in the token.

Bottom line is, there's nothing Cygwin can do about this.  Did you
look into the security event long?  Maybe there's a hint why this
fails.
