Proposed resolution:

Change 6 [fs.filesystem.synopsis]:

      enum class directory_options;
      {
      none,
      follow_directory_symlink,
      skip_permission_denied
      };

Add the following sub-section:

10.4 Enum class directory_options [enum.directory_options]

The enum class type directory_options is a bitmask type (C++11 §17.5.2.1.3) that specifies bitmask constants used to identify directory traversal options.

Name	Value	Meaning
none	0	(Default) Skip directory symlinks, permission denied is error.
follow_directory_symlink	1	Follow rather than skip directory symlinks.
skip_permission_denied	2	Skip directories that would otherwise result in permission denied errors.

Addresses: filesys.ts

enum class directory_options has no summary.
