* Makefile.in (GTHREAD_FLAGS): New var. (LIBGCC2_CFLAGS): Added $(GTHREAD_FLAGS). (distclean): Remove gthr-default.h. * configure.in: Accept dce as a thread package. Check for thread.h and pthread.h. Link gthr-default.h to appropriate thread file and set gthread_flags. (hppa1.1-*-hpux10*): If --enable-threads, use dce threads and include multilib definitions from pa/t-dce-thr. (sparc-*-solaris2*): Enable threads by default, if thread.h or pthread.h is found, preferring posix threads over solaris ones. * config/pa/t-dce-thr: New file. * config/pa/t-pa: Removed multilibs. * config/sparc/t-sol2: Ditto. * gthr.h: New file. * gthr-single.h: New file. * gthr-posix.h: New file. * gthr-solaris.h: New file. * gthr-dce.h: New file. * libgcc-thr.h: Removed. * objc/thr-dce.c: New file copied from thr-decosf1.c. * frame.c: Include gthr.h instead of libgcc-thr.h. * libgcc2.c: Include gthr.h instead of libgcc-thr.h. (eh_context_initialize): If __gthread_once fails, use static eh context. (eh_context_free): Call __gthread_key_dtor. From-SVN: r17235
