boehm-gc PR libgcj/13212: * configure.ac: Check for pthread_getattr_np(). Remove GC_PTHREAD_SYM_VERSION detection. * include/gc.h (GC_register_my_thread, GC_unregister_my_thread, GC_get_thread_stack_base): New declarations. * pthread_support.c (GC_register_my_thread, GC_unregister_my_thread, GC_get_thread_stack_base): New functions. (GC_delete_thread): Don't try to free the first_thread. * misc.c (GC_init_inner): Use GC_get_thread_stack_base() if possible. (pthread_create_, constr): Removed. (pthread_create): Don't rename. * include/gc_ext_config.h.in: Rebuilt. * include/gc_pthread_redirects.h (pthread_create): Define unconditionally. * include/gc_config.h.in: Rebuilt. * configure: Rebuilt. libjava * java/lang/natThread.cc (_Jv_AttachCurrentThread): Attach thread to GC. (_Jv_DetachCurrentThread): Detach thread from GC. * include/boehm-gc.h (_Jv_GCAttachThread, _Jv_GCDetachThread): Declare. * boehm.cc (_Jv_GCAttachThread): New function. (_Jv_GCDetachThread): Likewise. From-SVN: r116313
