Need clarification on compilation errors in PG 16.2

Hi ,
While we try to install PG 16.2 from the source code in macbook we getting
this following errors
```

*explicit_bzero.c:22:9: error: call to undeclared function 'memset_s'; ISO
C99 and later do not support implicit function declarations
[-Wimplicit-function-declaration] (void) memset_s(buf, len, 0,
len); ^explicit_bzero.c:22:9: note: did you mean
'memset'?/Library/Developer/CommandLineTools/SDKs/MacOSX14.2.sdk/usr/include/string.h:74:7:
note: 'memset' declared herevoid memset(void __b, int __c, size_t
__len); ^1 error generated.make[2]: *** [explicit_bzero.o] Error
1make[2]: *** Waiting for unfinished jobs....make[1]: ***
[all-port-recurse] Error 2make: *** [all-src-recurse] Error 2*
```
then I changed the function memset_s(buf, len, 0, len) to memset(buf, 0,
len) and it's working. need a clarification on this?

Thanks and regards
Pradeep
