--- Comment #2 from Martin Sebor <msebor at redhat dot com> ---
The GCC -fno-builtin-memset option can be used to prevent compatible compilers
from optimizing away calls to memset that aren't strictly speaking necessary.
Regarding portability: memset_s is an optional feature of the C11 standard and
as such isn't really portable. (AFAIK, there also are no conforming C11
implementations that provide the optional Annex K in which the function is
defined.)
