c++: defaulted op== 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 friend.
gcc/testsuite/ChangeLog:
* g++.dg/cpp2a/spaceship-eq17.C: New test.
