[Discuss-gnuradio] Exports in _runtime_swig.pyd

[Gisle Vanem]

I'm still trying to understand the build-process and internals of 
GnuRadio. While trying to build the Swig .pyd modules, I notice that 
gnuradio-runtime/swig/runtime_swig.i has a:
 #define GR_RUNTIME_API

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?
