Me three.

Daniel, the tests finished.  Things look horrendous, but better.

For example:

FAIL: gcc.c-torture/compile/930623-1.c (test for excess errors)
Excess errors:
/source/uber/gcc/testsuite/gcc.c-torture/compile/930623-1.c:7: error: insn does
not satisfy its constraints:
(insn 104 146 58 (set (reg:DI 33 1)
        (mem:DI (plus:SI (reg/f:SI 31 31)
                (const_int 48 [0x30])) [0 S8 A8])) 338 {*movdi_internal32} (nil)    (nil))

But this is much better than the current status.  Feel free to commit
if you haven't already done so.

Thanks.
