[PATCH] D35174: [libc++] Fix unrepresentable enum for clang-cl unstable ABI

[Eric Fiselier via Phabricator via cfe-commits]

EricWF added a comment.

Maybe using a static const variable instead of an enum would work better? `__long_mask` should never actually be ODR used so a definition for it should never actually be needed.
