OK, but I want to keep the dependencies list small. So it hurts in that
the user has to install additional packages. And if not including it
doesn't decrease functionality, then why not just leave it as a build-time
option?

OK, but it's not in the distro. I'll have to make a package.

What about GGI, SDL and OpenGL? I can build with the last two. GGI is not
in the distro.
What about ALSA, arts and NAS? I can build with arts and I don't think
there's any point in supporting NAS, it's no longer being developed, AFAIK.
ALSA is not in the distro, either.
What about lirc? I don't have it and it's not in the distro.
I suppose I should include vorbis ogg.
And, last but not least, what about win32/dshow codec support?

Ha! You changed it. Until recently it was enabled by default. Guess I'd
better check configure options each time I get a new CVS snapshot.

So if I --enable-runtime-detection, then I can safely turn all these
features on, is that it? Good.
