Thanks!

But it seems that the above settings are still imperfect, since they
mixes tabs and spaces when aligning. For instance:

int some_function(int some_variable)
{
<T>	int result;
<T>	result = execute_another_function(some_variable,
<T>	<T>	<T>	<T>	<T>	..other_variable);
<T>	return result;
}

<T> - represents tab here, `.' - space

And if one change the tab size, it will result in a messy alignment in
line 5.
I guess there is no ideal solution for this in Emacs.
