Mon Dec 13 12:20:00 1999 Richard Frith-Macdonald <richard@brainstorm.co.uk>
Fixes for cball's changes (who is cball?, and why didn't s/he produce
a ChangeLog entry or conform to GNU indentation? It took me hours to
tidy this up).
* Source/NSDate.m: ([NSGDate -addTimeInterval:]) removed bogus
implementation of method (inherits from NSDate).
* Source/NSCalendarDate.m: Added implementation of ([-addTimeInterval:])
with specific code for NSCalendarDate. Reformatted code to GNUstep
style.
* Source/NSGArray.m: ([-removeObjectIdenticalTo:]) and
([-removeObjectIdenticalTo:inRange:]) reverted to correct code.
([-removeObject:]) and ([-removeObjectIdenticalTo:inRange:]) removed
changes and added fixes so that methods are safe where multiple objects
equal to the object to be removed are present in the array.
* Source/NSArray.m: Similar fixes for object removal.
* Source/NSObject.m: Rewritten mutex code so that mutexes are not used
for retain/release unless the app is multi-threaded.
Wed Dec 1 19:36:00 1999 Richard Frith-Macdonald <richard@brainstorm.co.uk>
* Source/NSArray.m: When sorting, treat illegal return values from the
