        * cp-tree.h (defer_mangling_aliases): Declare.
        (generate_mangling_aliases): New prototype.
        * decl2.c (defer_mangling_aliases): New variable.
        (note_mangling_alias): Use !defer_mangling_aliases
        instead of at_eof.
        (generate_mangling_aliases): No longer static. Clear
        defer_mangling_aliases.
        * optimize.c (maybe_thunk_body): Defer emitting mangling aliases
        if !defer_mangling_aliases until the fns are put into the same
        comdat group.

        * g++.dg/abi/mangle67.C: New test.
