/*
  note on __attribute__ ((nocommon))
    AVR scripts often use  --gc-sections on the linker to remove unused section.
    This works fine for initialed data and text sections. In principle .bss is also
    handled, but the name##_pb definition is not removed. Reason is, that
    array definitions are placed in the COMMON section, by default
    The attribute "nocommon" removes this automatic assignment to the
    COMMON section and directly puts it into .bss. As a result, if more
    than one buffer is defined in one file, then it will be removed with --gc-sections

    .. not sure if Arduino IDE uses -fno-common... if yes, then the attribute is
    redundant.
