emacs-w32 shouldn't require dbus-daemon, as far as I know.  This sounds 
like a bug.  Could you give me a specific recipe for reproducing the 
problem?  And it couldn't hurt to send cygcheck output also.

Again, please send a recipe for producing the problem with the Gtk build.

If it turns out to be necessary, which I doubt, you can simply put the 
following in your .bashrc (assuming you use bash as your shell):

if [ -z "$DBUS_SESSION_BUS_ADDRESS" ] ; then
     eval `dbus-launch --sh-syntax`
fi
