By default, V2 builds all libraries as shared, both on Linux and Windows. On 
Linux, shared libraries just work. On Windows, you need to add some 
__dllexport attributes to functions/classes defined in qlist.c, otherwise no 
symbol will be exported and msvc linker will bypass generating of import 
library (the one with .lib suffix).

I suspect you already know this, but your Jamfile does not have the setup 
necessary for dynamic linking on Windows. Typycally, you'll put:

  <link>shared:<define>CTLLIB_SHARED=1

to your requirements, and use some macros in your headers to make sure 
__dllexport/__dllimport are set up properly when CTLLIB_SHARED is set to 1.
