If you are suggesting that a Windows compiler change should be invisible 
to non-Windows users, I agree.

Let us assume that /pcbuild remains for those who have vc2008 and that 
/pcbuild14 is added (and everything else remains as is). Then the only 
other thing that would change is the Windows installer released on 
Python.org. Call than 2.7.9W or whatever on the download site and 
interactive startup message to signal that something is different.
