I have regenerated stubs with the patch applied and it does resolve the
compilation problems. Thanks.

> I receive this failure both with the WSDL2C released in Axis2-1.3 and in the
> current nightly build I downloaded yesterday. Of course, it is a little
> difficult to isolate what in the WSDL is causing the failure, as no stub code
> is generated that might hint at the problem area. The same WSDL is accepted
> by the Axis2 WSDL2Java utility, so the issue is specific to C code
> generation. As the WSDL2Java utility accepts the file, this suggests that
> the WSDL itself is valid. If -d none is specified on the command line, the
> WSDL2C utility runs to completion, so the issue is specific to the generation
> of the C data bindings.
