[2.7] bpo-32616: Disable computed gotos by default for clang < 5 by methane · Pull Request #5574 · python/cpython (original) (raw)

I'm sorry, I'm not familiar with configure.ac.
As my understanding, configure just define HAVE_COMPUTED_GOTOS automatically.
USE_COMPUTED_GOTOS is never defined automatically, unless --with(out)-computed-gotos
is specified.

This pull request is just change behavior when USE_COMPUTED_GOTOS is not defined.
