[ruby-core:75030] [Ruby trunk Bug#12284] io-console gem >= 0.4.3 breaks on Windows ruby < 2.2.0 due to needing rb_sym2str

Issue #12284 has been updated by Jon Bailey.


The new gem appears to have installed without problems, thank you!  Will rubygems pick it up when the version number is next bumped?

* ruby -v: ruby 2.1.8p440 (2015-12-16 revision 53160) [x64-mingw32]
* Backport: 2.1: DONTNEED, 2.2: DONTNEED, 2.3: DONTNEED
----------------------------------------
Ruby 2.1.x users (on Windows) who do "gem update" and try to build io-console 0.4.3 or later fail at link-time.

rb_sym2str was first used in console.c in r50427

rb_sym2str was implemented in ruby 2.20

Excerpt of build failure:
`current directory: C:/rubytest/ruby-2.1.8-x64-mingw32/lib/ruby/gems/2.1.0/gems/io-console-0.4.5
make "DESTDIR="
