[PATCH] D33080: [Libc++] Use #pragma push_macro/pop_macro to better handle min/max on Windows

[Eric Fiselier via Phabricator via cfe-commits]

EricWF updated this revision to Diff 98725.
EricWF added a comment.

- Fix missing `_LIBCPP_POP_MACROS` in `<__threading_support>`.
- Add test that each header is unaffected by `min` and `max` macros and that the macros themselves are unaffected.
