Issue #9456 has been updated by Eric Hodel.


RDoc needs a racc runtime to parse the RD (rdtool) documentation in the ruby sources.

----------------------------------------
Bug #9456: Include bin/racc with ruby
https://bugs.ruby-lang.org/issues/9456#change-44667

* Author: Zachary Scott
* Status: Open
* Priority: Normal
* Assignee: Minero Aoki
* Category: 
* Target version: current: 2.2.0
* ruby -v: 2.2.0dev
* Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
As you [can see](https://github.com/ruby/ruby/tree/trunk/bin) we include executables for Rake, RDoc, ri, ERB, RubyGems, and Irb with Ruby.

We should also include Racc as an executable for Ruby.

This resolves an issue where libraries requiring Racc, and using the binary executable, must install the Racc gem in order to use bin/racc.

I'm fairly sure this change won't cause any issues, so I'd be happy to commit it.
