    c++: repeated friend template [PR101894]

    Since olddecl isn't a definition, it doesn't get DECL_FRIEND_CONTEXT, so we
    need to copy it from newdecl when we merge the declarations.

            PR c++/101894

    gcc/cp/ChangeLog:

            * decl.c (duplicate_decls): Copy DECL_FRIEND_CONTEXT.

    gcc/testsuite/ChangeLog:

            * g++.dg/lookup/friend22.C: New test.
