        * include/win32-threads.h (_Jv_ConditionVariable_t): Now a struct, to
	enable safer wait() algorithm.
	(_Jv_CondWait, _Jv_CondInit, _Jv_CondDestroy, _Jv_CondNotify,
	_Jv_CondNotifyAll): Implementations moved to win32-threads.cc.
	(_Jv_MutexInit, _Jv_HaveMutexDestroy, _Jv_MutexUnlock,
	_Jv_MutexLock, _Jv_ThreadYield): Reimplement using CRITICAL_SECTIONs
	instead of mutex.
	(_Jv_ThreadYield): Don't call Sleep(), because it crashes win98.
