Other possible implementations of pthread_once +will still be investigated for a possible future release in an attempt +to reduce the current implementation's complexity. + +All of the bug fixes and new features in this release have been +back-ported for relese 1.8.0. + +Bugs fixed +---------- + +* Fixed pthread_once race (failures on an MP system). Thanks to +Tim Theisen for running exhaustive pre-release testing on his MP system +using a range of compilers: + VC++ 6 + VC++ 7.1 + Intel C++ version 8.0 +All tests passed. +Some minor speed improvements were also done. + +* Fix integer overrun error in pthread_mutex_timedlock() - missed when +sem_timedwait() was fixed in release 2.2.0. This rouitne no longer returns +ENOSUP when NEED_SEM is defined - it is supported (NEED_SEM is only +required for WinCE versions prior to 3.0). + +* Fix timeout bug in sem_timedwait(). +- Thanks to Stephan Mueller for reporting, providing diagnositic output +and test code. + +* Fix several problems in the NEED_SEM conditionally included code. +NEED_SEM included code is provided for systems that don't implement W32 +semaphores, such as WinCE prior to version 3.0. An alternate implementation +of POSIX semaphores is built using W32 events for these systems when +NEED_SEM is defined. This code has been completely rewritten in this +release to reuse most of the default POSIX semaphore code, and particularly, +to implement all of the sem_* routines supported by pthreads-win32. Tim +Theisen also run the test suite over the NEED_SEM code on his MP system. All +tests passed. + +* The library now builds without errors for the Borland Builder 5.5 compiler. + +New features +------------ + +* pthread_mutex_timedlock() and all sem_* routines provided by +pthreads-win32 are now implemented for WinCE versions prior to 3.0. Those +versions did not implement W32 semaphores.
