One of the mysteries of the way Windows makes its dynamically linked
libraries (might be consistent with other systems, not sure) is that
the DLL is created as an "executable" and any of the symbols that it
exports are placed into the .lib.  The .lib is linked into the target
executable, and that library stub with those methods knows to look for
the DLL file to execute it in the proper way.  Without the .lib file,
the linker has no idea where to link the unresolved externals in the
executable so that they can call the necessary code in the DLL.  It
took me a long time to find that, since I was just used to seeing .a
and .so on Linux.
