cygwin dbus port patches

Just one suggestion: It would perhaps be good to make it more
explicitly clear in some README file that the Cygwin port of dbus has
nothing to do with, and does not interoperate with, the Windows port.
Otherwise there will be a risk that people confuse the two. There are
always now and then people who don't understand the fundamental
differences, that Cygwin really is a separate OS (that just happens to
run on top of Windows).
