    c++: member vs global template [PR106310]

    For backward compatibility we still want to allow patterns like
    this->A<T>::foo, but the template keyword in a qualified name is
    specifically to specify that a dependent name is a template, so don't l=
ook
    in the enclosing scope at all.

    Also fix handling of dependent bases: if member lookup in the current
    instantiation fails and we have dependent bases, the lookup is dependen=
t.
    We were already handling that for the case where lookup in the enclosing
    scope also fails, but we also want it to affect that lookup itself.

            PR c++/106310

    gcc/cp/ChangeLog:

            * parser.cc (cp_parser_template_name): Skip non-member
            lookup after the template keyword.
            (cp_parser_lookup_name): Pass down template_keyword_p.

    gcc/testsuite/ChangeLog:

            * g++.dg/template/template-keyword4.C: New test.=
