[libcxx-commits] [PATCH] D156508: [libc++][Modules] Fix a few module related warnings

[Ian Anderson via Phabricator via libcxx-commits]

iana added a comment.

An example warning I'm hitting locally:

  In module 'std_private_algorithm_copy_n' imported from /.../usr/include/c++/v1/__string/char_traits.h:12:
  /.../usr/include/c++/v1/__algorithm/copy_n.h:57:1: warning: inline function 'std::copy_n<const char *, unsigned long, char *>' is not defined [-Wundefined-inline]
  copy_n(_InputIterator __first, _Size __orig_n, _OutputIterator __result)
  ^
  /.../usr/include/c++/v1/__string/char_traits.h:242:14: note: used here
          std::copy_n(__s2, __n, __s1);
               ^

The only way I could find to fix that warning was to make the `std_private_string_char_traits` module `export *`.
