I would like to apply the following patch, which seems to give a
substantial performance improvement on Cygwin (and obviously has no
effect on other platforms).

This reverses a change made by Eli on 2006-01-27. Rationale: The time
when Cygwin didn't have d_ino in dirent was a brief period around
December 2005, and it applied only to Cygwin 1.5.19, which has long been
obsolete.
Any objections? If not, I would apply it to the emacs-23 branch and let
it propagate to the trunk.
