Yes, but:

   $ if [ -d /tmp/foo ] ; then echo yes ; else echo no ; fi

The existence check is because foo == foo.exe == foo.lnk under Cygwin, but the original complaint came from someone checking for a directory.  So, the lesson is, fix the stat(2)/test(1) call, don’t change Cygwin to cope with a bad test.
