## 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.

## Arguments
ARGS=$4; _ARGS=-$4; __ARGS=`echo $_ARGS | tr ',' '-'`

# Save up the argument list in a file; but only if argument has changed
#DIFF doesn't like empty files - so put a blank if empty
