No, it doesn't include it. This would probably fix libsdl1.2, but
another upload of this package is then needed. It won't fix all the
other broken packages that have to be fixed the same way.

If we want to go for this solution, we have to scan the archive for
usage of this header file, and fix them by submitting a patch. With the
hope it won't come in a middle of a transition.

Having libusb-1.0 support is something really interesting. However, it
doesn't fix application that directly use the kernel API. That's the
case of all applications I have listed.
