Clearly you understand the main issue here.  I believe its fixable although
I'm not sure that making the library a DLL in itself will addresse it.
Basically we have to find the tweak so that there is one and only one type
table be it in the main program or in the DLL of the library.  I'm sure it
will require a subtle adjustment in the library.  If you managed to figure
this out let me know.  I'll also take a look at it.
