    c++: defaulted op=3D=3D for incomplete class [PR107291]

    After complaining about lack of friendship, we should not try to go on =
and
    define the defaulted comparison operator anyway.

            PR c++/107291

    gcc/cp/ChangeLog:

            * method.cc (early_check_defaulted_comparison): Fail if not fri=
end.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp2a/spaceship-eq17.C: New test.
