It's not exactly a bug.  The reason for this is a change in the
opendir/readdir/closedir implementation.  The old implementation used
Win32 functions in a way which opened a handle to the directory only
when the first readdir has been called.  The new implementation opens
the handle already on opendir.  Make calls opendir on the foo/bar
directory as a result of the implicit rule, but not readdir, so there
was no open handle in the old implementation, but there is an open
handle now.

I have a new implementation of unlinking files which should help here,
too.  I'll look into using this method for rmdir as well.

However, this will not be available in the upcoming 1.5.24 release.


Thanks for the report,
Corinna
