Re: [Jython-dev] Building Jython3

[Jeff A. <ja...@fa...>]

It fails either way for me (-S or not), and with the same error Isaiah 
reports. However, I'm just impressed it compiles the 3.5 std lib.

When I say "the same error", I can tell that from debug, but in fact it 
dies trying to print the error because it can't find the right codec 
(cp850). I'm not phased though, as I've solved that before. 
(https://hg.python.org/jython/file/tip/src/org/python/core/Py.java#l1345) 
Lot's to chew on here.
