C++ front-end produces:
<<cleanup_point const int signs_all[4] = {0};>>;
<<cleanup_point signs_all[0] = (int) sx <= 0 >>>;

While the C front-end is producing:
const int signs_all[4] = {(int) sx <= 0, (int) sy <= 0, (int) sz <= 0,
0};
Dale Johannesen and I came up with a patch to the C++ front-end
for this except it did not work with some C++ cases.
Yes, we had it in Apple's branch for a while and had to back it out.
The place to look is split_nonconstant_init in cp/typeck2.c if you want
to try. The tricky part is making sure the entire object is
initialized in all cases when only a partial initializer is specified.
