Fixed in svn revision 621 (2008-10-27).

These are coming from the use of the Py_RETURN_TRUE and Py_RETURN_FALSE
macros defined by Python.h.
So the fix will need to be a change to the Python sources, not a change to
distcc.

But as mentioned in my earlier email, you can work around it using the
--disable-Werror option when configuring distcc.

Likewise for these ones.

Thanks for the feedback!
