Motivation It's tempting for us to use the FILE * for stderr whenever we want to print to it. However, the Linux libc modules aren't appropriately annotated to call that field constant, and indeed it isn't. This causes Swift to throw a fit if we even touch it. Modifications Introduce an awkward function that issues direct writes to stderr instead of using the FILE *. Result Swift is happier.
