Alain,

For the current code I think your patch a tad better. It uses one less
instruction. Short of benchmarking the two solutions I think yours is
the one that should go in. Would you please submit a patch that
includes the assemble_SCS function as well. After you submit it with
that change and a notice that you have singed off on it. I'll nominate
it over my own to go in.

Conn
