By using char const * instead of std::string we avoid significant
copying per assertion. In a simple loop with 10000000 CHECKS on
my system, this reduces the run time from 9.8s to 5.8s.
This change is at the expense of no longer capturing the second arg,
which no currently existing test notices.
-add macros to test for C++ version and features
to catch_compiler_capabilities.hpp
- replaces dynamic exception specifications (deprecated)
with noexcept in C++ Version >= 11
- defines defaulted copy constructor/move constructors/assignment
in C++ Version >= 11 since their implicit generation is deprecated
under some circumstances.
- fixes#259
