* sysdeps/generic/Makefile (make_siglist): Add missing backslash. * sysdeps/generic/dl-sysdep.c (_dl_sysdep_start_cleanup): New function. * hurd/hurdfault.c: Replace __libc_fatal calls with assert_perror. (_hurdsig_fault_init): Remove #if 0 from setting exception port. Insert send right for SIGEXC before thread_set_special_port. * hurd/hurdsig.c: Replace __libc_fatal calls with assert_perror. (_hurdsig_init): Remove #if 0 from setting exception port. * sysdeps/mach/hurd/ptrace.c (ptrace: PTRACE_CONT): Use HURD_MSGPORT_RPC macro.
