The are 2 failures.

One can be fixed simply by patching test/automated/package-test.el in
the following way:

     (should (equal (macro-problem-10-and-90) '(10 90)))))

My question is: when you ``(require 'macro-problem)'',
should the package mechanism be clever enough to reload the files
when you upgrade the package? Because clearly it doesn't happen
there.

Second problem directly related to the underlying platform: the
connection to http://0.0.0.0:8000/ fails with a 10049 error.
This error is frequently reported on forums (see
http://www.sockets.com/err_lst1.htm for example).
I don't know what is the best fix.
