How to deal with noexcept in Visual Studio

Question

I\'m trying to create a custom exception that derives from std::exception and overrides what(). At first, I wrote it like this:

class U         


        

Answer 1

This check works to see if noexcept is supported:

// Is noexcept supported?
#if defined(__clang__) && __has_feature(cxx_noexcept) || \
    defined(__GXX_EXPERIMENTAL_CXX0X__) && __GNUC__ * 10 + __GNUC_MINOR__ >= 46 || \
    defined(_MSC_FULL_VER) && _MSC_FULL_VER >= 180021114
#  define NOEXCEPT noexcept
#else
#  define NOEXCEPT
#endif

The above works with Clang, GCC and MSVC.
