Amaury Forgeot d'Arc added the comment: The 3.2 change r85656 removes OPT:Olimit, IMO this should not be backported. But 2.7 already has this warning fixed for icc: http://hg.python.org/cpython/rev/e7c96c1d144b/ We should do the same here. What's the correct way to detect Oracle Studio compiler

R. David Murray added the comment: I agree, it is the job of the autotools to handle system portability issues such as this, and thus this can be considered a fixable bug. However, it is the kind of thing that is only going to get fixed if someone whom it affects can propose a patch, since I dou
