It seems that many of us disagree, and nobody has agreed with you.  Do you
have a citation?

The C standard specifies the behavior of library functions.  If the
compiler knows how to provide this behavior without actually calling into
the system C library, it is allowed to.  Both are parts of the
implementation.
