Unnecessary typedef in generated code for bus objects

Hi all,

I want to generate code for a model. This model contains one bus object named "bdv_MeasAndUsability".

When I generate code (R2012a) for my model, I do not see a struct "bdv_MeasAndUsability" in the generated c code.

Instead I see a typedef to "struct_JYoJISpxnLe7EdSldVmzWE", see below.

Why is there that indirection with the "struct_JYoJISpxnLe7EdSldVmzWE"?

Is it possible to suppress that indirection?

#ifndef _DEFINED_TYPEDEF_FOR_struct_JYoJISpxnLe7EdSldVmzWE_
#define _DEFINED_TYPEDEF_FOR_struct_JYoJISpxnLe7EdSldVmzWE_

typedef struct {
  real_T meas;
  boolean_T isUsable;
} struct_JYoJISpxnLe7EdSldVmzWE;

#endif

#ifndef _DEFINED_TYPEDEF_FOR_bdv_MeasAndUsability_
#define _DEFINED_TYPEDEF_FOR_bdv_MeasAndUsability_

typedef struct_JYoJISpxnLe7EdSldVmzWE bdv_MeasAndUsability;

#endif
