Is it possible to use #define macros in stateflow?

Hello all,

I'm involved with converting old C code to Stateflow. In C, many #define macros are used. I'd like to use them also in stateflow. For example, in a c header file, i have the following macro:

   #define ENABLE_IGBT output1=1;

Then I used this in a stateflow transaction:

   {
   ENABLE_IGBT
   }

During Code Generation, Matlab puts out a warning: "Transition (#5076) has an action with no side effect." In C code, the stateflow transaction is missing. #defines in the same c header file like

   #define TEST_VALUE 123

work without any problems in stateflow. I'm using R2014a. Where's the fault?

It would be helpful if you would provide the model on which you are working.
