I lied. This was short enough that I didn’t do that.
Next one for sure! (says Bullwinkle).

This patch fixes two tests that were failing when built with libc++/c++11.
The problem is in the tests - they were comparing two ostream & for equality.

Strictly speaking, that’s not allowed. 
What was happening in C++03 was that they were being implicitly converted to void *, and the pointers compared. (this allowed the “if ( !stream)” idiom.
In C++11, the conversion is to bool (not void *), and it is explicit - so this code no longer compiles:
        std::cout == std::cout.

I changed the tests to use a different structure there, one with an actual operator==.
(and removed some tabs)

This should give Boost.Function an (almost) completely green test matrix.
