Yes it was defined in "pg_config.h"
/* Define to 1 if you have the `memset_s' function. */
#define HAVE_MEMSET_S 1
Thanks

In fact, whether the HAVE_MEMSET_S macro is defined determines whether the implementation
of the explicit_bzero() function calls memset_s() or memset(). This macro is undefined by default
in pg_config.h, so check to see if your build environment has a HAVE_MEMSET_S macro defined.
