Likewise.  I think that it would be very good to compare build 
performance of non-recursive builds (such as for my own package) with 
more traditional recursive builds.  The non-recurisive build offers 
more opportunity for speed-up since it makes more of the targets 
candidates to be built and avoids unnecessary use of the linker or 
archiver.
