Yeah, I don't think gdb's DWARF reader will or should try to do what
dwarflint does.  But I also doubt we'll ever remove the complaints from
dwarf2read.c; and of course gdb may emit complaints that dwarflint will
not (e.g., for valid but odd stuff not handled by gdb).  And, given that
we will probably always have complaint calls, I think they should
provide enough information to actually find the problem DIE.
