Overview
Comment:Code for Simulink S-function target written direct to sfun.cc instead of
calling .mexglx files. This eliminates the sfun dependency on Octave
ColumnVectors. sys_sfun.cc should build directly on a MS Windows machine
(can't test this yet).

added sfun.zip target to create source code to export.
