I should have mentioned that vector_c<...> is an mpl template
and I probably should have appended a ::type.

I just uploaded another version which calculates the offset
for a given fixed vector of indices and fixed shape for a
hypothetical array.  The test is in function
test_array_index_offset in the aforementioned .zip file.
