ftp://ftp.oarcorp.com/pub/rtems/cd-working

It closes the following PRs:

[NOTE: Hopefully next time I will know how to automate the GNATS
query so we will see the PR synopsis with that list. :)

Corresponding documentation is at:

http://www.oarcorp.com/rtemsdoc-4.6.0-pre/

I hope this is the final preview before the release.  But feedback is 
needed.

Thanks
