Not strictly, no. I believe in my brief tests, just the int cast was
sufficient. I can respin if you'd like. I probably need to anyway to

Thoughtless copying on my part. Glibc actually uses sizeof(__fd_mask),
but that is a typedef long int. I'm pretty sure that varianet doesn't
make things better.
