        the most bizzare bug ever (I *think* it may be a compiler but, but it

        YSI_gCharacterS were the same and YSI_gBotC and YSI_gCharacterC were the
        same).  Adding print statements which reference these variables seem to fix
        the problem, and I've tried to make sure that the values will never actually
        get printed.

Function:
        Itter_InitInternal
Params:
        array[][] - Itterator array to initialise.
        s0 - Size of first dimension.
        s1 - Size of second dimension.
Return:
        -
Notes:
        Multi-dimensional arrays can't be initialised at compile time, so need to be
        done at run time, which is slightly annoying.
