At one point in the past, libsdl-*1.2-dev packages didn't depend on the
libsdl1.2-dev package, causing a FTBFS. If you look at the changelog, you will see:

    - Added libsdl1.2-dev to Build-deps (fix FTBFS)

That was in Feisty, and it's fixed now, so we can remove it. But why would you
remove it? You shouldn't rely on dependencies of your build-dependencies, since
in the future they can change, causing a FTBFS. If you have a dependency on a
package, shouldn't you put it, regardless of the other build-dependencies?

We don't do binary-only rebuilds AFAIK, but that isn't a excuse not to fix it ;)

I mailed (more than once) to Isaac Clerencia, who is the Debian Maintainer, and
he told me he was going to add it. Maybe he forgot about it...

Also, I sent him this patch. Feel free to apply it too!

I'll remember to CC you next time I change wesnoth in Ubuntu!
