User-defined data type und RTW?

Hi,

according to the documentation of simulink, the user-defined data types can
be used in the s-function, so that s-function block can correctly handle
with I/O signals of any user-defined types. we have no problem by compiling
this s-function into C-MEX file and by running our model including this
s-function block. Unforturnately, we can not compile and build our model
using RTW.
There is the following error:
#C0020 identifier "ssRegisterDataType_cannot_be_used_in_RTW" is undefined
#C0020 identifier "ssSetDataTypeSize_cannot_be_used_in_RTW" is undefined

Could anyone tell me how to avoid this problem?
Thanks you very much in advance!

With kind regards

Was this issue ever resolved? I am getting the following using Matlab2007b+
error: `ssGetDataTypeAccess_cannot_be_used_in_RTW' undeclared

From the doc (http://www.mathworks.com/help/simulink/sfg/ssregisterdatatype.html)

"The Simulink Coder product does not support S-functions that contain custom data types. Attempting to generate code for a model that contains this macro results in an error."
