They all get applied as part of the build.  The current target is to
remove most of them by having them pushed upstream.

Personally, if the build fails on a patch, I reapply it against the
current sources and fix any conflicts.  I have a script to speed this
up.  It just greps the patch, and creates two directory trees
containing the appropriate original files form OpenJDK.  I then apply
the patch to one and resolve any issues, before creating a new patch.
It may not be the most efficient way but it works for me and has been
well-tested.  I'm reluctant to trust the process to a tool I don't
know very well, especially if that tool is expected to work for all
developers using IcedTea.  It just seems to complicate things
unnecessarily IMO.

The time spent switching to quilt would be better spent getting
patches upstream.
