Just on the language issues:

Let's be precise here please (the point is moot anyway because we have
c99), but since you brought it up: You can always introduce a scoping
block in the middle of your code and add declarations in the beginning
of it so it is not really a serious limitation.
	{
		int x;
	}
In ways actually declaring variables in the middle of your code
can introduce more bugs specially if you use goto:

	if (error)
		goto out;
	int i = 0;
out:
	return i;

It is a matter of programming style. If you are willing to lose a
little efficiency you can always hide the implementation and write
constructor and destructor functions in c.

typedef struct foo foo_t;

foo_t *x = create_foo(args);
	doit_with_foo(x);
	destroy_foo(x);

I don't disagree with the c++ implementation choice, but personally I would
have preferred to have a java implementation instead...
