just a wild guess:
under linux (like k_jack~) linking is very dirty - you can use all 
(non-static) functions that are defined somewhere.

windows is exporting is done more properly: functions have to be 
explicitly declared to be exported.
now sys_open_audio() is *not* exported by pd; thus you cannot access it 
under windows but it is possible under linux.

workaround: use the EXPORT macro (m_pd.h) to make sys_open_audio() 
available to externals.
