You are thinking of pre-ISO compilers that only allow initialization of auto
scalar members.  ISC C89 (and presumably C99) does allow initialization of auto
arrays and structures (though if you aren't going to modify it, you should
declare it static to avoid having to do the copy at runtime).  What is a GCC
extension to C89 (I don't remember about C99) is an initialization to an
array/struct that doesn't involve static members:

	int foo(int i){
	  auto struct bar { int a, int b; } s = { i, 0 };
	}
