Missing headers?

[P. Durante]

Hi,
I just noticed that in my dbus installation are missing some header
files which the documentation reports to belong to the _public_
interface, they are dbus-timeout.h and dbus-watch.h, did the packager
of Ubuntu (the distribution I'm using) miss them or are we just not
supposed to use them ?
I needed them while implementing a dbus server, but maybe I'm doing it
the wrong way, suggestions ?

regards,
Paul
