So, perhaps we can use something like

#if defined(Q_CC_MSVC)
#  define Q_DECL_NOEXCEPT throw()
#  define Q_DECL_NOEXCEPT_TYPE(x)
#elif defined(QT_CXX_EXCEPTIONS)
#  define Q_DECL_NOEXCEPT noexcept(true)
#  define Q_DECL_NOEXCEPT_TYPE(x) noexcept(x)
#else
#  define Q_DECL_NOEXCEPT
#  define Q_DECL_NOEXCEPT_TYPE(x)
#endif
