If I remember it correctly, it's because of some Unices from ca. 1990-1994.
They have <stddef.h>, and when used with GCC, they support ANSI C. But
some of them don't have any wide-character facilities. I think SunOS 4
is one of them. Maybe also some more recent but virtually unmaintained
commercial BSDs.
