libiberty/cp-demangle.c.  For my suggestion, you would need to edit
d_bare_function_type like this:

    peek = d_peek_char (di);
    if (peek == 'J')
      {
        d_advance (di, 1);
        has_return_type = 1;
      }

Yes.  The file libiberty/cp-demangle.c is shared by all the projects,
so the source code patch would go over right away, but older
binutils/gdb releases would of course not work with the new mangled
names.
