* Headers/Foundation/NSLock.h
Completely rewritten implementations of NSLock.h classes. These are now
faster, more complete, OS X-compatible, and most importantly actually
work. The old ones, for example, called functions that were not
implemented on Windows.
* Source/NSThread.m
Call pthread functions directly in NSThread instead of via the libobjc
abstraction layer. Also fixed a few issues, such as GC not being
initialized properly for NSThread subclasses that override -main (Javaism
supported by OS X) and tidies up the code in several places, removing
premature optimizations, especially those that introduce a test for an
unlikely case at the start of a method and thus slow everything down.
As a result of this change, GNUstep now depends on an implementation of
POSIX threads. This is included as standard on all modern UNIX systems,
and as an option on less-modern UNIX systems and non-UNIX systems,
including Windows. If you are building GNUstep on Windows, please install
the pthreads-win32 package, available from:
http://sourceware.org/pthreads-win32/
PLEASE TEST THIS! There may be some code that depended on the old
behaviour. I have been running the new NSLock implementation on FreeBSD
for a few weeks without issue; please report to me any problems that you
have on your platform.

inconsistency between Cocoa (and OpenStep) and GNUstep.
Reinstatement of correction for bug #25307. Testing on both OpenStep
and on Cocoa clearly illustrates that throwing an exception in this
case was incorrect. It now emits a warning when the lock is attempted
again, but does not throw an exception.
* Testing/locktest/locktest.m: Change to test to correctly test
[NSConditionLock lock]

thr-mach.h header.
* Source/thr-mach.h: Moved here from
Headers/Additions/GNUstepBase/thr-mach.h.
* Source/NSLock.m: Include private thr-mach.h header for

apple-gnu-gnu.
* Source/thr-mach.m: Include private thr-mach.h header from
new location.
* Source/thr-pthread.m: Ditto.

forward declaration.
* Headers/Additions/GNUstepBase/GSCategories.h: Remove
declaraion of gnustep_global_lock.
(GS_INITIALIZED_LOCK): New macro.
(+[NSLock newLockAt:]): New method.
(+[NSRecursiveLock newLockAt:]): Ditto.

* Source/Additions/GSCategories.m: Replace global lock with
local lock.
(_GSLockInitializer): New class to initialize local lock
safely.
(newLockAt): New static function shared by +newLockAt:
implementations to safely intialize lock variables.

(+[NSRecursiveLock newLockAt:]): Ditto.
* Source/Additions/GSCompatibility.m: Remove
gnustep_global_lock.
* Source/Additions/GSObjCRuntime.m: Remove superfluous
locking.
* Source/Additions/Unicode.m: Use new GS_INITIALIZED_LOCK
macro and replace global lock with local lock.

- initWithString didn't deal with adjacent format
specifiers.
NSDate.m - addTimeInterval messed up timezone if used with
CalendarDate.
NSArray.m - NSMutableArray's comparered against a garbage pointer
NSGArray.m on removal. This causes real problems on SMP machines.
NSTimeZone.m - The GMT+-xx files on OpenStep are in the root directory
and they are in Etc/* in gnustep so check both.
NSObject.m - The release code was slightly broken for SMP machine
use.
NSLock.m - Trylock was broken and lockBeforeDate unimplemented.

directly in source files because the config.h file is system

not be installed.
