    Subject[PATCH 02/13] Always expose __SYSCALL(... fork ...)
    Date
    I think this change actually doesn't do anything: __NR_fork was still
    being defined either way, and on my machine fork() in <unistd.h> comes
    from libc.

    That said, I don't think there's any way to determine this
    automatically, so this at least quiets the checker.
