This happens because ospell.h (in hfst-ospell) contains member function 
definitions. When the header is included in libvoikko these member functions 
will have hidden visibility and default visibility when they are included in 

I would fix this by moving the member function definitions from ospell.h to 
ospell.cc and re-compiling both hfst-ospell and libvoikko. This would avoid 
the extra definition within libvoikko (where at least get_key_table() is not 
even used). But this will be API incompatible change in hfst-ospell so I'm not 
sure if you want to do it.
