[swift-dev] Inability to leverage privacy in the stdlib

[Slava Pestov]

It will become the default, but not yet, so yeah, you shouldn’t merge anything that only builds with this flag set.

Can you share the patch that adds private modifiers along with the linker errors you are seeing? Now would be a good time to sort out these issues.
