Ouch, this is bizarre. Anyway, looking at the comments in gcc.jam I see this:

        # On windows (cygwin) i.e. <target-os>cygwin
        #     libxxx.a     static library
        #     xxx.dll      DLL
        #     libxxx.dll.a import library

So the code was *supposed* to use .dll extension on windows, but did not
for some reason. Please commit the patch. Thanks!
