I know that way in above code already,

What I insist to discuss here is I think this may be a gcc's bug,
could be fixed in some future day?

before an `=' to specify a nested subobject to initialize; the list is
taken relative to the subobject corresponding to the closest
surrounding brace pair. For example, with the `struct point'
declaration above:
struct point ptarray[10] = { [2].y = yv2, [2].x = xv2, [0].x = xv0 };

For anyone could succeed compiling gcc-4.6, could you paste a correct
ggc_alloc_cleared_lang_type macro ?
just run this grep command under your build directory,
gcc-4.6-build$ grep -RsInw ggc_alloc_cleared_lang_type gcc/
gcc/gtype-desc.h:2451:#define ggc_alloc_cleared_lang_type() ((struct

No, just a very simple configure and make command:
../path/to/gcc-4.6-build$ time { ../gcc-4.6-20100911/configure

The problematic gtype-desc.h has been sent to Laurynas separately, I

The GCC has default support of dumping gimple cfg in vcg format, but when I
was trying to find a tool to interpret the *.006t.vcg dump file, or to generate
a vector image format, it seemed not easy, the vcgviewer [1] not mature as
Graphviz, and Graph::Easy [2] is a
