Original commit message from CVS: * removed gstreamer.m4 (packages should use pkg.m4) * guilaunch depends only on gtk, not libglade-gnome * removed an unnecessary check in dynamic-pipeline.c * attempted to avoid a spurious autoheader run * gtk2 fixes * killed a lot of files that automake brings in for us * killed acinclude.m4, it's autogenerated
