<stdio.h>: like <stddef.h>, this provides only pieces if __need_FILE or
__need___FILE is defined
<stdlib.h>: likewise, but for __need_malloc_and_calloc
<string.h> and <wctype.h> are straightforward
<wchar.h> is tricky: C libraries that don't implement the right interface
provide non-const-correct functions like "wchar_t *wmemchr(const wchar_t*,
wchar_t, size_t)". We can't fix that, so we don't try.
