* 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.
