defined, don't worry about Sun's silly LBRAC bug.
* config/m68k/tm-sun3.h: Define SUN_FIXED_LBRAC_BUG to 0.
* dbxread.c (process_one_symbol): If there's a symbol before an
N_SO, don't error().
(case N_BCOMM): complain () not error ().
* defs.h, main.c (catch_errors): Add return_mask arg.
stack.c (print_frame_info): Pass RETURN_MASK_ERROR.
other callers: Pass RETURN_MASK_ALL.
