* hurd/hurdinit.c (_hurd_ports_use): Return error _hurd_ports is null.
* hurd/hurdsig.c (_hurdsig_init): Conditionalize exception port setup for old CMU and new OSF Mach interface flavors. * hurd/hurdfault.c (_hurdsig_fault_init): Likewise. * sysdeps/mach/hurd/fork.c (__fork): Likewise. * hurd/hurdsig.c (_hurd_internal_post_signal): Leave msgh_seqno unset. * sysdeps/mach/hurd/spawni.c (__spawni) [KERN_INVALID_LEDGER]: Pass extra arguments to task_create for OSF variant. * sysdeps/mach/hurd/fork.c (__fork): Likewise.
