Only "conforming hosted implementations" are required to
provide the whole library. A "conforming freestanding
implementation" of ANSI/ISO C need only provide float.h,
limits.h, stdarg.h, stddef.h.

In a freestanding environment you can't even rely on the
string functions, let alone things like fopen and malloc.
