    For your 5.10 version this: archname=i686-linux-thread-multi and these: useithreads=define, usemultiplicity=define & this  USE_ITHREADS are all telling you it is compiled for multi-threading.

    Conversely, your 5.8.8 has this: archname=i686-linux and these:usethreads=undef use5005threads=undef useithreads=undef usemultiplicity=undef telling you it is not.

    With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
    "Science is about questioning the status quo. Questioning authority".
    In the absence of evidence, opinion is indistinguishable from prejudice.
