Warning while compiling dbus 0.34

[John (J5) Palmieri]

That is just the Pyrex python module generator being stupid.  I brought
up these issues with the upstream maintainers and their response was,
"it would complicate the code too much to fix the issues".  The lvalue
warnings however have been fixed (they used to be errors or at least
error out on fedora's gcc).  You can grab the patch from the fedora RPM
of Pyrex if you want.  It should be showing up when they do the next
release of Pyrex upstream hopefully.
