The linker must resolve dynamically linked objects to a dll
entry point.  Linking with a DLL is done in an almost transparent way.
You simply link with the existing .lib file.  Now if what you mean
is making a binding to an existing library, then you can
use pragma Import.  Use C as the calling convention unless
the calling convention is STDCALL in which case use stdcall.
Also, note that for DLL data you should use stdcall to insure
indirect references are generated.
