* hurd/hurdselect.c (_hurd_select) [MACH_MSG_TRAILER_MINIMUM_SIZE]:
Use untyped Mach IPC message format.
* sysdeps/mach/hurd/ioctl.c (__ioctl) [! MACH_MSG_TYPE_BIT]: Handle
Handle untyped Mach IPC message formats.
* hurd/catch-exc.c (_S_catch_exception_raise) [EXC_MASK_ALL]:
Expect different argument conventions when this is defined.
[EXC_MASK_ALL] (_S_catch_exception_raise_state): New stub function.
[EXC_MASK_ALL] (_S_catch_exception_raise_state_identity): Likewise.
* hurd/hurdfault.c: Likewise for _hurdsig_fault_catch_exception_*.
[NDR_CHAR_ASCII] (mig_reply_header_t): #define as mig_reply_error_t
for OSF Mach variant.
(faulted): Use mig_reply_error_t for REPLY.
(_hurdsig_fault_init) [EXC_MASK_ALL]: Use EXCEPTION_STATE_IDENTITY
in __thread_set_exception_ports call.
(_hurdsig_fault_init) [MACH_PORT_RECEIVE_STATUS]: Use
__mach_port_set_attributes in place of __mach_port_set_qlimit.
* sysdeps/mach/powerpc/sysdep.h (_MACH_MACHINE_ASM_H): Define this
before include <sysdeps/mach/sysdep.h>, to inhibit <mach/machine/asm.h>
on Darwin, which includes bogons.
