    c++: bogus -Wvexing-parse with trailing-return-type [PR118718]

    This warning should not warn for

      auto f1 () -> auto;

    because that cannot be confused with initializing a variable.

            PR c++/118718

    gcc/cp/ChangeLog:

            * parser.cc (warn_about_ambiguous_parse): Don't warn when a
trailing
            return type is present.

    gcc/testsuite/ChangeLog:

            * g++.dg/warn/Wvexing-parse10.C: New test.
