    Avoid warning for ignoring chown() return value on some glibc's,
    and change compiler from cc to gcc. Sometimes the (void) before
    chown() is not sufficient to signal the programmer's intent to
    ignore the return value. (Thank you return-value police.) This
    commit kills that gcc warning just for copymeta(). Using pragma
    then required ignoring a warning for versions of gcc that don't
    recognize it (when using -Wall). Finally, gcc is used instead of
    cc for platforms that don't make that equivalency.
