Re: plmerge crash in latest trunk

[David Chisnall]

Perhaps I'm missing something, but wouldn't leaving this line in  
NSZone.m have avoided breaking the ABI:

NSZone* __nszone_private_hidden_default_zone = &default_zone;

Code including the new header would not access this variable, but code  
already linked would.
