Cygwin's CV> open(2) call uses these flags by default. well, CreateFile() accepts 0 as second argument, which is what we need-- just query information no matter if anyone opened file in DENYALL mode. i've just tested it on nt4.0 -- it works fine. the only question is whether we should add new parameter to fhandler::open(), say 'int cygwin_flags', or define new flag in fcntl.h? for me, the first one looks preferable.
