Why is rtw_extmode.h included in the header file even if not using Real-Time Workshop in external mode for a model that uses model referencing in Simulink 6.0 (R14)?

I have a model in Simulink 6.0 (R14) that uses model referencing. All the configuration sets are set such that they do not use external mode. However, Real-Time Workshop includes the following line of code in the generated header files.

#include "rtw_extmode.h"

This bug has been fixed in Release 14 Service Pack 2 (R14SP2). For previous releases, please read below for any possible workarounds:

We have verified that there is a bug in Real-Time Workshop 6.0 (R14) in the way that it handles code generation in external mode.

This issue is known to occur when either of the following conditions exists:

- You select Simulation-->Configuration Parameters-->Real-Time Workshop-->Interface-->Utility function generation-->Shared location.

- The model contains a referenced model.

To work around this issue,

1. Edit $MATLAB/rtw/c/tlc/mw/commonhdrlib.tlc, where $MATLAB is the MATLAB root directory on your machine, as returned by typing

matlabroot

at the MATLAB command prompt.)

2. Search for the following string:

%if ::ExtMode == 1 || CompiledModel.GenUtilsSrcInSharedLocation

You should find only one occurrence.

3. Replace the string with the following:

%if ::ExtMode == 1

4. Close the file.

5. Restart MATLAB.

6. Issue the following command at the MATLAB command prompt:
