    The RedHat bug suggests 'static const' as the appropriate replacement.

    https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=114610#c4

    Unfortunately that probably means an extra 64 bytes of text, rather than
    the 10 or so bytes of instructions to do the memset and store. Ideally
    padding[] would be allocated in BSS rather than text or the stack (and
    initialized with { 0x80, } at runtime), but I guess you can't have
    everything.
