I encountered a couple of problems on Windows:
   1.   build.bat --with-python=D:\Python\2.5
         does not work. The final call to bootstrap\jam0 gets:
                    --with-python D:\Python\2.5
         without '='. I suppose that '=' is treated as argument
separator by cmd.exe
         and gets eaten in Setup_Args loop. I solved this by removing the
         Setup_Args loop and using %* in the call to jam0.  This is supported
         since Windows 2000, I am not sure about earlier versions.

   2.  bjam.exe --build-system=pybb
        in python\tests\bjam\make also fails, because os.uname() is
not supported
        on Windows:

------------------
     Perhaps using the more portable platform.uname() would work, but
I don't know if it returns the same names as os.uname().
