these are generated improperly because of an extraneous condition in
dbxout_symbol. The patch is:

  		   || (GET_CODE (XEXP (DECL_RTL (decl), 0)) == REG
  		       && REGNO (XEXP (DECL_RTL (decl), 0)) != FRAME_POINTER_REGNUM)))

briefly, since TREE_CODE(decl) is known to be VAR_DECL, the nuked comparison
always fails. When it is removed, a "correct" (w/in bounds of dbx
brain damage) stab entry is produced.
