[PATCH] D103929: [clang] P2085R0: Consistent defaulted comparisons

[Alexandru Octavian Buțiu via Phabricator via cfe-commits]

predator5047 added a comment.

Regarding

  struct A;
  bool operator==(A, A);
  struct A {
    friend bool operator==(A, A) = default; // error, not first declaration
  };

GCC and msvc have marked P2085R0 as complete and do not implement this rule 
should I  implement it anyway? 
I don't know if clang  would rather adhere to the spec or do the same as  gcc 
and msvc.
