Correct, bitsets (and bitmask types in general) aren't required to support 
operator&&.

Looks like a bug in the MS implementation to me, the test case appears to be 
something like:

typedef int (&func_ref)(float, double);
typedef result_of<function_ref(float,double)>::type result_type; // error 
here.
