Compiling a threads DLL using VC6

I just downloaded Boost and am trying to do some development using it. Our product will be developed and fielded on both Win2K and Solaris. So far I've been using Boost solely on VC6, and I have a question regarding building the threads library. I've gotten the build to run correctly, but it doesn't seem to build a DLL version of the library. I looked in the both the runtime-link-static and runtime-link-dynamic dirs, and both contain only a .LIB version of the library. Is there something I'm doing wrong here? Or am I misunderstanding what should be generated? Any clarification or pointers would be greatly welcomed. Thanx, Steve Dussinger
