the code below sounds like this with supercollider 3.5.2 (32bit) running under 10.8.2 on a macbook pro.
it's how i'd like it and it's great compared to the other versions.

s.waitForBoot{	
	SynthDef(\birdy, {|out= 0, amp= 0.1, freq= 1000, atk= 0.01, rel= 0.05, cur= -4, gate= 1|
		var env= EnvGen.kr(Env.asr(atk, 1, rel, cur), gate, doneAction:2);
		var src= SinOsc.ar(0.11, BRF.ar(SinOsc.ar(SinOsc.ar(0.12).exprange(1, freq), 2pi), 1/SinOsc.ar(0.13).range(1, #[99, 100])));
		Out.ar(out, Limiter.ar(LeakDC.ar(src*amp)));
	}).add;
	s.sync;
	Synth(\birdy, [\amp, 0.15]);

the code below sounds like this with supercollider 3.5.7 (64bit) running under 10.8.2 on a macbook pro.
it's utterly wrong and boring compared to the sc3.5.2 version.

	SynthDef(\birdy, {|out= 0, amp= 0.1, freq= 1000, atk= 0.01, rel= 0.05, cur= -4, gate= 1|

		Out.ar(out, Limiter.ar(LeakDC.ar(src*amp)));
	}).add;
	s.sync;
