Oh, really? I couldn't reproduce that effect on my system (Debian Linux
64-bit) with dmd (latest git) and gdc (git gdc-4.7 branch). I always get
the same ordering regardless of the compiler I used.

For reference, here's my code:

	import std.file;
	import std.stdio;

	void main(string[] args) {
		auto entries = dirEntries(args.length > 1 ? args[1] : ".",
					SpanMode.shallow);

		foreach (e; entries) {
			writeln(e);
		}
	}
