Well, I'm really not sure. I just found this difference between linux
and cygwin (st_stat is 0 for dirs on cygwin). Than I noticed that the
routine where I made the change explicitely checks for st_size not
being 0. I must admit I can't make much out of comment, and hope this
discussion will help to clear the check up.

Could you, just for completeness, try? I don't have mingw at hand
and SUSv3 (http://www.opengroup.org/onlinepubs/009695399/toc.htm)
does not tells much too. No UNIX system I know about has it 0 for
directories.
