Hi,
I want to assure GC is on for my app. I did try adding PRINT_GC=YES to 
my Environment and THAT says that it is indeed on (or atleast that my 
app requires it).
objc[3069]: GC: executable '/Users/dominik/Sources/objectiveC/
DimeTracker/build/Debug/DimeTracker.app/Contents/MacOS/DimeTracker' 
requires GC
objc[3069]: GC: library '/System/Library/Frameworks/
ApplicationServices.framework/Versions/A/Frameworks/CoreText.framework/
Versions/A/CoreText' supports GC
objc[3069]: GC: library '/System/Library/PrivateFrameworks/

But asking NSGarbageCollector I get no for an answer:
- (void)awakeFromNib {
   if([[NSGarbageCollector defaultCollector] isEnabled])
       NSLog(@"GC on");
   else
       NSLog(@"GC off");

Did I simply not understand the docs right? Or..... is GC always off 
during awakeFromNib or something?

Thanks,
Dominik
