MATLAB: “Unresolved symbols found” at parsing. Symbols supposed to be included from a header file

Question

I have made a Stateflow diagram with two states. One of the transition is "after(d1,CLK)" d1 is a constant which is supposed to be declared outside Simulink, somehow included from a header file. That makes sense if you use "Real time workshop" to generate code. As it is now, every time I parse the chart I get "Unresolved symbols found" complaining about d1. I have seen it is possible to use constants outside Simulink. I just don't know how to do it. Can somebody help?

You need to add the header to the Simulation Target->Custom Code->Header File pane of the model Configuration Parameters window. See Integrating Custom C Code for Nonlibrary Charts for Simulation.
