Hi Shea,

Excellent, thanks for the patch!  Looks good to me.

A few notes:

Could you change the patch to make it work in ‘trunk’ without requiring
a complete rebuild?  This way we could already use 4.6 with ‘trunk’,
even if stdenv still uses 4.5.

To that end, you need to svn cp ppl/{default.nix,0.11.nix} and use the
latter for 4.6, while keeping the former for 4.5.  Same for CLooG-PPL.

OK.  I modified ‘update-gcc.sh’ in the ‘stdenv-updates’ branch, but that
should be OK.

Thanks!
