MKL Sparse BLAS: different MKL_INT types?

1) Is there a way to call into both the LP64 and ILP64 versions of MKL Sparse BLAS routines like mkl_dcsrmv(), from the *same* C++ program?

2) In future releases, would the MKL developers consider allowing users to *redefine* MKL_INT to different integral types? In my use-case, I have many small sparse matrices whose indices can be represented by 8- and 16-bit integers, so there's potential 2-to-8-fold memory footprint savings (w.r.t. indexing data) versus using the MKL defaults.Thanks! --Nick
