[Pyrex] Compiling Pyrex generated code breaks with GCC4.0

[John (J5) Palmieri]

Not sure if you guys are aware of this but Red Hat has just moved their
development branch to compiling with GCC 4.0.  I ran into problem
recompiling the D-Bus python bindings which are written in Pyrex. 
Basically GCC 4.0 is very strict about using casts especially casting
lvalues (which is the errors I get).  I'm going to look into it further
to see if I can't provide a patch when I find time.  Just want to find
out if it is a known problem and if anyone already made a fix.  Thanks.
