I think we all know that dhrystone is a bad benchmark. But some users don't.
Which is more difficult: educating all users about that vs apply a simple patch
in GCC to remove the useless initialization? 4.4 does has such initialization.
But 4.5 has. Fixing this is an improvement and does not hurt. From another
point, leaving it unfixed does not help GCC.
