* Compiler specific macro definitions.
*
* WSREP_NOEXCEPT - Specifies that the method/function does not throw. If
* and exception is thrown inside, std::terminate is called
* without propagating the exception.
* Set to "noexcept" if the compiler supports it, otherwise
* left empty.
* WSREP_NORETURN - Indicates that the method/function does not return.
* Set to attribute "[[noreturn]]" if the compiler supports,
* it, otherwise "__attribute__((noreturn))".
* WSREP_OVERRIDE - Set to "override" if the compiler supports it, otherwise
* left empty.
* WSREP_UNUSED - Can be used to mark variables which may be present in
* debug builds but not in release builds.
