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.

NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
{ } [pool drain];
