Proposed resolution:

Add a new sub-section:

5.2 Feature test macros [fs.req.macros]

This macro allows users to determine which version of this Technical Specification is supported by header <experimental/filesystem>.

Header <experimental/filesystem> shall supply the following macro definition:
#define __cpp_lib_experimental_filesystem     201406
[Note: The value of macro __cpp_lib_experimental_filesystem is yyyymm where yyyy is the year and mm the month when the version of the Technical Specification was completed. — end note]

SD-6: SG10 Feature Test Recommendations recommends that each library header provide feature test macros. For Technical Specifications, the TS itself should specify recommended names for the feature test macros.
