Re: Building Jython3

I found the same problems and fixed them too. And one that prevents me 
compiling on Windows. In the case of the "from __future__" problem I 
solved it differently.

I will open a PR for this as a way of exercising the CPython process 
(see thread about that). It will conflict with the new tip, but that's 
ok because resolving merge conflicts is also a use case to learn. I have 
to do this slowly, however, with the Git Book and dev guide open!
