Feature #5157: [PATCH] add -Wunused-variable to CFLAGS
http://redmine.ruby-lang.org/issues/5157

Author: Eric Wong
Status: Assigned
Priority: Low
Assignee: Motohiro KOSAKI
Category: build
Target version: 1.9.x


Unused variables are ugly.

As an often-careless C extension maintainer, I end up with a lot of unused
variables, so this compiler flag will propagate to extensions I maintain.

The core of Ruby is remarkably free of unused variables despite the
current lack of -Wunused-variable, however I've also attached a trivial
patch to the openssl extension that removes a few unused variables.
