By the way, thanks for pointing out that using constexpr suppresses the warning
on GCC. Although Clang does not support constexpr in C yet, it is interesting
that Clang is smart enough to not warn about a plain const:
const int a = 1;
unsigned int b = 2;
if (a < b) // warning here on GCC, but not on Clang
puts("a < b");
I imagine that it would be difficult to change GCC's behavior to match Clang's
in this case.
