Noted, but blocked by the wheezy release freeze. If you need to develop
i386 applications on an amd64 system under Debian wheezy, you will need
an i386 chroot, or possibly (less reliably) a mostly-amd64 multiarch chroot
that contains libdbus-1-dev:i386 instead of libdbus-1-dev:amd64.

We do have hardware-dependent headers, making dbus a non-trivial case
of multiarch -dev (just like glib2.0):
/usr/lib/TUPLE/dbus-1.0/include/dbus/dbus-arch-deps.h embeds knowledge
of word sizes, because D-Bus is portable to platforms like Windows/MSVC++
which do not have a C99 stdint.h or inttypes.h.

libdbus-1-dev also depends on pkg-config, but pkg-config is not
multiarch-ready yet (#631275). Ubuntu's pkg-config 0.26-1ubuntu1 would
probably work. Blocking this bug accordingly.
