If I understand correctly, you have user code which provides a header
called "version", and now when files like <utility> include <version> they
pick up the user header instead of the STL one?
Are you specifying custom libc++ include paths when this occurs? Or just
passing "-stdlib=libc++" and letting the compiler do the rest?
In general, I don't consider this a bug. There is no way for libc++ to make
the <version> file disappear in older dialects, and libc++ headers are free
to include w/e additional headers
they need.
