Just to point this out : When Dag and I were searching for agreements on
many diverging points in our ways of building packages, one we easily got
to was to have the default (i.e. "without any manual defines") rebuild for
the latest release of the distribution available.

In this case, this means that if someone checks for %{fedora}'s value, but
it isn't defined, the behavior should default to the proper one for FC4
(since it's the latest ATM). For me, this is a sane default, and I'd like
to see Extras use it as much as possible too ;-)

So "if %fedora >= 4 then foo else bar" should be replaced by something
else that works as expected (like what Ignacio wrote).
