Summary: dynamic_cast used in generated code (even with "nortti")

Initial Comment:
Hi,
I am trying to build my libraries with RTTI disabled (-fno-rtti GCC flag) and I am using the SWIG directors functionality. 
The problem is that even with -nortti SWIG flag the generated code contains dynamic_cast at one place (in "disown" function) while at other places the SWIG_DIRECTOR_CAST macro is used properly.
I found a user, who submitted a patch for this issue, but unfortunately it was in Ubuntu launchpad and got lost (https://bugs.launchpad.net/ubuntu/+source/swig1.3/+bug/210898).

Please, would it be possible to apply the fix? It is a one-line change and it is obviously correct.

For the time being I am using the following command as a post-processing step:

sed 's/Swig::Director \*director = dynamic_cast<Swig::Director \*>(arg1);/Swig::Director \*director = SWIG_DIRECTOR_CAST(arg1);/g' -i ${LIBNAME}PYTHON_wrap.cxx

Thank you very much.
Kind regards,
Filodej
