    Please read my mail again, icc already supports my_array[0], but the
    resulting array in the binary has size '1'. The actual showstopper is
    the output of genassym.sh. To me it seems it's just a genassym.sh issue,
    but I don't really know what's going on in the kernel, so I ask here.

    Bye,
    Alexander.
