[cfe-dev] [libcxx] RFC: C++14 and beyond

Hello,

The same standard that clang uses for compilation (-std=c++xx). Not sure if that would work with
gcc, though.

This might also be a problem when libc++ is shipped with the OS (as is the case on MacOS X).

By appropriately defining a configuration macro (like the already existing _LIBCPP_DEBUG2).

How do the inline namespaces that libc++ already uses play into this?


My 2 cents,
