* hurd/intr-msg.c: Use INTR_MSG_TRAP macro from machine-dependent "intr-msg.h" for special syscall code, instead of i386-specific asm. * hurd/hurdsig.c: Use INTR_MSG_BACK_OUT macro from machine-dependent "intr-msg.h" before mutating thread state to skip RPC. * sysdeps/mach/hurd/i386/trampoline.c: If PC is inside _hurd_intr_rpc_mach_msg special syscall code, use real SP saved in %ecx. * Makeconfig (link-libc): New variable; use shared library if available. (+link): Use it. * sysdeps/mach/hurd/fork.c (_hurd_fork_locks): Variable removed. Instead, declare with `symbol_set_declare'. (fork): Use symbol_set_* macros for _hurd_fork_locks. Use SS->thread instead of __mach_thread_self (). Suspend all other threads during task_create and port copying.
