This is a good point.  For GraphicsMagick we just had to deal with it 
and provide an external way to know how the library was expected to 
have been compiled.

This is fragile since it is possible/likely that both static and DLL 
are available at the same time and compiler will choose one of them 
according to its own rules, and especially if libtool is not used for 
linking against that library.
