From a quick look, it looks good. Can you chase down the packages that
had their own workaround for the lack of queue.h ?

At the moment, I see only libtirpc, but I might have missed others. If
you could prepare a patch for those packages to make them use the now
globally available queue.h, it would be good.

Thanks!
