No, we cannot: it's a temporary fix. The flag causes compilation error if it's added to old version of clang or to a C compiler different than clang.

I don't think that it's a matter of performance here. What matters the most here is correctness.

See Florian Weimer's message:
https://bugs.python.org/issue36618#msg340261

"This issue potentially affects all compilers, not just Clang."
