Thus functions/vars in _runtime_swig.pyd gets a dllexport linkage.
But comparing to gnuradio-runtime/swig/pmt_swig.i there is no
PMT_API at the top. Why the difference?
Further to the problem I had with linking in the Swig code for this:
extern const pmt_t PMT_T; (in pmt_swig.i)
This may work fine with the GNU linker, but MSVC needs explicit
dllimport. So I patched pmt_swig.i like this:
--- pmt_swig.i.orig 2014-09-24 13:48:36 +0000
+++ pmt_swig.i 2014-10-19 14:51:19 +0000

<pmt/pmt.h> already has the proper import decoration. No point declaring
those with 'extern'. So now .py examples using _pmt_swig.pyd works just
fine.
I noted in the Ettus Gr installation, there where no _pmt_swig.pyd.
Maybe that's due to the problem they had with link that on Windows.
Seems imposible w/o correct DLL-linkage.
