See gcc-3.4-20030924/gcc/config/rs6000/altivec.md, line 673.  Change
vmsumubm to vmsummbm.  That is, the bug persists through this snapshot.

    667 (define_insn "altivec_vmsummbm"
    668   [(set (match_operand:V4SI 0 "register_operand" "=v")
    669         (unspec:V4SI [(match_operand:V16QI 1 "register_operand" "v")
    670                       (match_operand:V16QI 2 "register_operand" "v")
    671                       (match_operand:V4SI 3 "register_operand" "v")] 66))]
    672   "TARGET_ALTIVEC"
    673   "vmsumubm %0,%1,%2,%3"
    674   [(set_attr "type" "veccomplex")])

BTW, on this bug submission page, there is no way to attach files to conform,
I think, to the guidelines.
