 Hi all,
 when compiling the Boost Test library with MSVC 2015 and warning C4946
 (reinterpret_cast between related types) set as an error, the build fails.
 The specific_param_error class uses reinterpret_cast in its operator
 functions (lines 89 and 99 in errors.hpp).

 I am aware that this warning is off by default but at least
 suppress_warnings.hpp should list this warning. Also, a comment in the
 source why a reinterpret_cast was necessary in the first place, would be
 helpful.
