        * init.c (constant_value_1): Treat a DECL_INITIAL of
        error_mark_node as meaning that the variable is uninitialized,
        rather than erroneously initialized.

        * g++.dg/init/self1.C: New test.
        * g++.dg/other/fold1.C: Adjust error markers.
        * g++.dg/init/member1.C: Likewise.

it
