OK, thanks.

I downloaded the qemu-1.4.1 release and looked at the pixman subdir. It
doesnt come with a generated configure script, but has a autogen.sh script to
run autoconf itself. My understanding was that, like you say, the user
shouldn't need to run autoconf to generate configure, it should have been
provided. Am I missing something?
