csup import?

["Jiawei Ye" <leafy@xxxxxxxxxxxxxxxxxx>]

Hi fellow DF users,

CSup is a cvsup replacement written in C (http://mu.org/~mux/csup.html). 
This was imported in to FreeBSD HEAD a few days ago and so far had proved to 
work in checkout mode. Do we have the incentive to import this into our 
system so that we don't need cvsup-bin?

There is a minor compilation error when I tried to build the latest snapshot 
from the site on DF-Preview

cc -O -pipe -march=k6-2 -I. -I/tmp/csup -g -pthread -DHAVE_FFLAGS -DNDEBUG

 -c globtree.c
In file included from globtree.c:31:

I'd appreciated if anyone would help getting this into our base system.
