Hi Rob,
I don't know of any way to make a dynamically linked library (.dll or .so) into a statically linked archive library (.lib or .a).
I believe you'll have to recompile the source of the two .dll's (or at minimum, ar together the .o files - presuming there's no DLL instrumentation that happens to the object files at compile time) as an archive library instead of a shared library.
