+ * pthread_cancel.c (pthread_cancel): Adapted to use auto-detected
+ QueueUserAPCEx features at run-time.
+ (ptw32_RegisterCancelation): Drop in replacement for QueueUserAPCEx()
+ if it can't be used. Provides older style non-preemptive async
+ cancelation.
+ * pthread_win32_attach_detach_np.c (pthread_win32_attach_np):
+ Auto-detect quserex.dll and the availability of alertdrv.sys;
+ initialise and close on process attach/detach.
+ * global.c (ptw32_register_cancelation): Pointer to either
+ QueueUserAPCEx() or ptw32_RegisterCancelation() depending on
+ availability. QueueUserAPCEx makes pre-emptive async cancelation
+ possible.
+ * implement.h: Add definitions and prototypes related to QueueUserAPC.

+
+ * QueueUserAPCEx (separate contributed package): Provides preemptive
+ APC feature.
+ * pthread_cancel.c (pthread_cancel): Initial integration of
+ QueueUserAPCEx into pthreads-win32 to provide true pre-emptive
+ async cancelation of threads, including blocked threads.

+
+ * pthread.h (DWORD_PTR): Define typedef for older MSVC.
+ * pthread_cancel.c (AMD64): Add architecture specific Context register.
+ * ptw32_getprocessors.c: Use correct types (DWORD_PTR) for mask
+ variables.

+
+ * ptw32_threadDestroy.c: Destroy threadLock mutex to
+ close a memory leak.

+
+ * pthread_equal.c: Remove redundant equality logic.
+
+2003-12-10 Philippe Di Cristo <philipped at voicebox.com>
+
+ * sem_timedwait.c (sem_timedwait): Fix timeout calculations.
+

+
+ * pthread_mutex_timedlock.c (ptw32_semwait): Move to individual module.
+ * ptw32_semwait.c: New module.
+ * pthread_cond_wait.c (ptw32_cond_wait_cleanup): Replace cancelable
+ sem_wait() call with non-cancelable ptw32_semwait() call.
+ * pthread.c (private.c): Re-order for inlining. GNU C warned that
+ function ptw32_semwait() was defined 'inline' after it was called.
+ * pthread_cond_signal.c (ptw32_cond_unblock): Likewise.
+ * pthread_delay_np.c: Disable Watcom warning with comment.
+ * *.c (process.h): Remove include from .c files. This is conditionally
+ included by the common project include files.
+

+
+ * ptw32_getprocessors.c: Some Win32 environments don't have
+ GetProcessAffinityMask(), so always return CPU count = 1 for them.
+ * config.h (NEED_PROCESSOR_AFFINITY_MASK): Define for WinCE.
+
+2003-10-15 Ross Johnson <ross at callisto.canberra.edu.au>
+
+ * Re-indented all .c files using default GNU style to remove assorted
+ editor ugliness (used GNU indent utility in default style).
+

+
+ * sem_init.c (sem_init): Would call CreateSemaphore even if the sema
+ struct calloc failed; was not freeing calloced memory if either
+ CreateSemaphore or CreateEvent failed.
+
+2003-10-14 Ross Johnson <ross at callisto.canberra.edu.au>
+
+ * pthread.h: Add Watcom compiler compatibility. Esssentially just add
+ the cdecl attribute to all exposed function prototypes so that Watcom
+ generates function call code compatible with non-Watcom built libraries.
+ By default, Watcom uses registers to pass function args if possible rather
+ than pushing to stack.
+ * semaphore.h: Likewise.
+ * sched.h: Likewise.
+ * pthread_cond_wait.c (ptw32_cond_wait_cleanup): Define with cdecl attribute
+ for Watcom compatibility. This routine is called via pthread_cleanup_push so
+ it had to match function arg definition.
+ * Wmakefile: New makefile for Watcom builds.
