For boehm-gc:

* configure.in: Rename THREADLIB to THREADLIBS.
	* Makefile.am (LINK): Add $(THREADLIBS) to libtool command line. This
	ensures that we link the correct version of the linuxthreads semaphore
	functions.
	* Makefile.in: Rebuilt.
	* configure: Rebuilt.

	* linux_thread.c (GC_thr_init, GC_suspend_handler): Add SIGABRT to the
	list of signals which are not blocked during suspend in the NO_SIGNALS
	case.

For libjava:
	* Makefile.am (libgcj_la_LIBADD): Add $(THREADLIBS). This ensures that
	the correct versions of various linuxthreads functions get linked.
	* Makefile.in: Rebuilt.
	* java/lang/natThread.cc (finalize_native): New static function. Call
	_Jv_ThreadDestroyData.
	(initialize_native): Register finalizer for "data".
	* include/posix-threads.h (_Jv_ThreadInitData): New simpler prototype.
	(_Jv_ThreadDestroyData): New prototype.
	* include/win32-threads.h: Ditto.
	* include/no-threads.h: Ditto.
	* posix-threads.cc (_Jv_ThreadInitData): Implement new prototype.
	(_Jv_ThreadDestroyData): New function. Free native thread "data" and
	move mutex and condition variable destroy code from:
	(really_start): ...here.
	(_Jv_ThreadStart): Set PTHREAD_CREATE_DETACHED.
	* win32-threads.cc (_Jv_ThreadInitData): Implement new prototype.
	(_Jv_ThreadDestroyData): Implemented.
	* nogc.cc (_Jv_AllocObject): Use "void *" not "ptr_t".
	(_Jv_AllocArray): Ditto.
