It worked on x86 gcc/clang where I tested it, but I was worried that
postgres supports many different platforms and could cause issues
somewhere.
But it's not an issue: after looking at it for a while I completely
forgot/ignored that the masking expression has several explicit casts,
so it is well defined in C11 and shouldn't cause warnings anywhere.
