The generated header file always contains real_T, regardless of this setting, found in the "Data Type Replacement" tab. I have tried C99 and C89/90.
I need to be using doubles. Seems like a bug?
Thanks!

You need to set up the replacement name.
You can choose to specify new data type names for some or all Simulink® built-in data types listed in the table. Specify the replacement name as one of the following:
  • A Simulink.AliasType object.
  • A Simulink.NumericType object.
  • The Simulink Name built-in data type name.
An error occurs, if:
  • A replacement data type specification is inconsistent with the Simulink Name data type.
  • The Simulink.AliasType object has the Data scope parameter set to Exported.
