Unimplemented core issue 1374: Conversion sequence ranks qualification before reference binding

The following code will print B, when both gcc and clang print A. This is due to a resolution to core issue 1374, which reorders the rankings of conversion sequences such that qualification difference are accounted for after reference binding differences, rather than before. #include <stdio.h> typedef int * T1; typedef int *const T2; void foo(T1 &) { printf("A\n"); } // (1) void foo(T2 &&) { printf("B\n"); } // (2) int main() {   foo((int *)0); // Normally prefers (2), but now prefers   return 0; // (1) in GNU and Clang modes. }
