    c++: concepts TS and explicit specialization [PR101098]

    duplicate_decls was not recognizing the explicit specialization as matc=
hing
    the implicit specialization of g<Y> because
    function_requirements_equivalent_p was seeing the C constraint on the
    implicit one and not on the explicit.

            PR c++/101098

    gcc/cp/ChangeLog:

            * decl.c (function_requirements_equivalent_p): Only compare
            trailing requirements on a specialization.

    gcc/testsuite/ChangeLog:

            * g++.dg/concepts/explicit-spec1.C: New test.=
