    Samba has the following check:

    # recent FreeBSD, NetBSD have creation timestamps called birthtime:
    AC_CHECK_MEMBERS([struct stat.st_birthtimespec.tv_nsec])
    AC_CHECK_MEMBERS([struct stat.st_birthtime], AC_CHECK_MEMBERS([struct stat.st_birthtimensec]))

    and the supporting code around that. "birth" might also be
    where the "b" comes from :-)
