tfpt review “/shelveset:Equality;REDMOND\tomat”
Comment :
Fixes comparisons of hashes, arrays and strings to behave according to
http://redmine.ruby-lang.org/repositories/revision/2?rev=3442

Adds specs for this behavior.

Also fixes:

(the failures are not critical any more, our behavior is now the same
as 1.8.6).

Fixes interop test assembly build so that it works on machine with
VS2010.

Test changes look good.
