__PRETTY_FUNCTION__ is slightly different in GCC 7

Browse Source 
The output of an unsigned int literal dosn't contain the u anymore.

	#include <iostream>

	template < typename T >
	struct ctti{
		template < unsigned int D = 1 >
		static constexpr auto name()noexcept{
			return __PRETTY_FUNCTION__;
		}
	};

	int main(){
		using ctti = ctti< int >;
		std::cout << ctti::name() << '\n';
	}
