bug#4186: 23.0.91; Can not compile CVS Emacs on Debian old-stable (dbus problem)

[Matthieu Moy <Matthieu.Moy@imag.fr>]

Hi,

Short version: whether I enable dbus or not, newest Emacs fails to
compile on my system.

Longer version:
With the same configuration I used to succeed in compiling Emacs on my
machine, I now get this error at link time:

dbusbind.o: In function `xd_remove_watch':
/home/moy/local/usr/src/emacs/src/dbusbind.c:766: undefined reference to `dbus_watch_get_unix_fd'
/home/moy/local/usr/src/emacs/src/dbusbind.c:768: undefined reference to `dbus_watch_get_socket'
dbusbind.o: In function `xd_add_watch':
/home/moy/local/usr/src/emacs/src/dbusbind.c:741: undefined reference to `dbus_watch_get_unix_fd'
/home/moy/local/usr/src/emacs/src/dbusbind.c:743: undefined reference to `dbus_watch_get_socket'
collect2: ld returned 1 exit status

Fine, I thought, my dbus is too old, I don't need it, I'll disable it.
But compiling with --without-dbus, it doesn't work either:

Wrote /net/bauges/local/moy/usr/src/emacs.git/lisp/net/tramp-ftp.elc
Compiling /net/bauges/local/moy/usr/src/emacs.git/lisp/net/tramp-gvfs.el
Loading tramp...

In toplevel form:
../../lisp/net/tramp-gvfs.el:101:1:Error: Symbol's function definition is void: dbus-init-bus
make[2]: *** [...] Error 1

Reproducible with a fresh checkout.

Ideally, Emacs should be tought not to use inexisting functions in
libdbus, but at least, fixing the build with --without-dbus should be
done.

Thanks in advance,
