Always worth asking, but in this case, I'm not sure it's appropriate.
The patch is pretty invasive, and I don't think the bug is a regression.
Also, 4.6 generates really lousy code for these i
Since it also affects 4.6 branch, can this and r176270 also be ported to gcc4.6?

Sorry for the breakage. It was due to a humiliating stupid mistake

Let's use num_split_elts so that it's clearer that we're counting the
number of elements that have been initialized outside t

However, such constants shouldn't be needed in normal use.
They came from an unnecessary zero-initialis
