    Fits: corrected compiler warning
    
    Samane Raji reported the 'ndim' variable was causing a "may be used
    uninitialized in this function" compiler warning. Although within the
    high-level logic we know this never happens, and newer compilers can tell,
    but its better to just initialize it to zero.
