    c++: Fix non-portable default argument of make_auto_1 [PR104197]

    Avoid using the macro current_template_depth, which expands to an
    expression that uses __FUNCTION__, within the signature of a function.

            PR c++/104197

    gcc/cp/ChangeLog:

            * pt.cc (make_auto_1): Use -1 as a placeholder default argument
            for level.
