* gbl-ctors.h: Lose HAVE_ATEXIT. Don't define ON_EXIT. * libgcc2.c: Lose obsolete defn of WEAK_ALIAS. (__bb_init_func, __bb_init_prg): Use atexit instead of ON_EXIT. (__do_global_dtors): Likewise. Don't mess with _exit_dummy_decl. (atexit, exit): Simplify. * tm.texi: Document NEED_ATEXIT and ON_EXIT. Remove HAVE_ATEXIT. * config/lots: Remove defns of HAVE_ATEXIT. From-SVN: r29439
