* 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.
