I use @synchronized in Objective-C++ built with Xcode 2.3 (using
ggc-4.0 [1] and have objective-c exceptions enabled) and I get
"warning: control reaches end of non-void function" when I specify
-Wall for the following code.

- (BlahParticipant*) getFirstOrganizer
{
   @synchronized (self) {
       return [[firstOrganizer copy] autorelease];
   }

You can't synchronize up the call stack. This is probably what you want:

- (BlahParticipant*) getFirstOrganizer
{
	id ret;
   @synchronized (self) {
       ret= [[firstOrganizer copy] autorelease];
   }
	return ret;
}
