Stefan

I'm not 100% I agree that this is a hack -- enabling people to specify
a python interpreter is useful outside of this difficulty. 

Still, the batch file solution also works; as you say, it's works for
other things also (DVC.el for instance!). I'll see whether I can get
this into the cygwin package so that it just does the right thing. 

Thanks for your help!
