Re: [RFA] stabsread and const/volatile vars

[Jim Blandy <jimb@zwingli.cygnus.com>]

As Elena pointed out in private E-mail, since GCC doesn't emit the
const and volatile stabs, this change won't have any effect.  However,
since the GCC folks often claim that they haven't enhanced GCC to emit
a particular kind of debug info because GDB wouldn't consume it, I
think this change is a good one --- it removes an excuse.  :)
