I find it strange to introduce real bools (which these macros return according to their official signatures) and then to assign them a meaning of a still-nonexistent but widely used C type. At least my C intuition stumbles upon that immediately, no matter how long I think about it.

Ah, anyway, standard C/libc is basically a lost cause. It can’t get any worse, since you have to refer to a manual at every call to not step on a landmine.
