This is upstream python bug 969718 offhand; basically if cflags exists 
for distutils consumers, base cflags don't make it fully through- 
meaning no -fno-strict-aliasing as is generally needed for building 
python extensions.

As for py3k, looks of it py3.1 still suffers it.


Either way, this is the wrong thing to fix- python's distutils 
needs fixing, not consumers.  In snakeoil, we detect and fix it on the 
fly to provide a fixed version of distutils, but obviously not many 
pkgs consume that...
