The usual equivalent older construct is this:
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; { } [pool drain]; which (AFAIK) does exactly the same thing as: @autoreleasepool { } but just a little less beautifully. Now the commit you referenced has this older construct still in place. But I didn't look at the current source code that you are compiling to see what it has.
