Here it is: http://bugs.python.org/issue12641

We need to tread carefully with the distutils codebase, as many setup
scripts out there depend on undocumented behavior or work around bugs.
For this issue, I don’t have enough information to decide whether to do
a version check, call gcc -dumpspecs or remove the option altogether.
