Upstream does have some build defines for BSD platforms:

• Unset _POSIX_C_SOURCE on FreeBSD
• Set _NETBSD_SOURCE on NetBSD

macOS is probably going to need something similar to get W_EXITCODE:

#if (!defined(_POSIX_C_SOURCE) || defined(_DARWIN_C_SOURCE))
#define WCOREDUMP(x)    (_W_INT(x) & WCOREFLAG)

#define W_EXITCODE(ret, sig)    ((ret) << 8 | (sig))
#define W_STOPCODE(sig)         ((sig) << 8 | _WSTOPPED)
#endif /* (!defined(_POSIX_C_SOURCE) || defined(_DARWIN_C_SOURCE)) */
