Created attachment 26015
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26015
gcc47-pr51229.patch

Untested fix.

This patch doesn't deal with missing diagnostics for invalid:

struct A { int i; };

int a = { .foo = 6 };
int b = { [0] = 1 };
_Complex float c = { .foo = 0,  1 };
_Complex float d = { [0] = 0,  1 };
_Complex float e = { 0, .foo = 1 };
_Complex float f = { 0, [0] = 1 };
char g[] = { [7] = "abcd" };

I'd prefer to leave that part to Jason.
