But memcpy from memcpy.S is returning a pointer to dest area.
That would lead to quasi non-portable code when the return from memcopy
is correctly checked depending on which memcopy function is addressed.
But BTW, is it meaningful to take into account a return code
that is always the same and which value is known in advance ?
Does memcpy suppose to failed in some cases ?
