Doesn't really matter. The point is that it has its own library
dependancies, and the interface is not fully pascal enabled. Then it doesn't
matter if it is statically linked (.a), dynamically linked at startup time,
or dynamically loaded over loadlib. 

IOW the division between mainprogram and lib is handcrafted, and the
problems are the same (shared state+memmgr,VMT, no way to check mismatch in
interface)
