* sysdeps/mach/configure.in: Check for <mach/machine/ndr_def.h>
or <machine/ndr_def.h> and add -DNDR_DEF_HEADER=... to DEFINES. * sysdeps/mach/configure: Regenerated. * mach/mach_init.c [NDR_DEF_HEADER]: #include it. * hurd/hurdfault.c (_hurdsig_fault_init): Add a cast. * hurd/hurd/signal.h: Include <setjmp.h> for `jmp_buf' decl. * mach/msgserver.c (__mach_msg_server_timeout) [! MACH_RCV_LARGE]: Double MAX_SIZE and don't retry on MACH_RCV_TOO_LARGE. * sysdeps/mach/hurd/times.c [NO_CREATION_TIME] (startup_time): New static variable. [NO_CREATION_TIME] (times_init): New static function in __libc_subinit. (__times) [NO_CREATION_TIME]: Use startup_time in lieu of task creation_time from task_basic_info. (__times): Use __gettimeofday instead of __host_get_time. * hurd/intr-msg.c (_hurd_intr_rpc_mach_msg) [! MACH_MSG_TYPE_BIT]: Use untyped Mach IPC message format. * hurd/catch-exc.c: Include <assert.h>, missing from last change.
