* hurd/Versions (libc: GLIBC_2.0): Add _S_catch_exception_raise_state,
_S_catch_exception_raise_state_identity, _hurdsig_fault_catch_exception_raise_state, _hurdsig_fault_catch_exception_raise_state_identity. * mach/shortcut.awk: Don't apply the /^}$/ rule when $proto == "". * sysdeps/mach/getsysstats.c (__get_avphys_pages) [HOST_VM_INFO]: Use __host_info with HOST_VM_INFO flavor instead of __vm_statistics. * sysdeps/mach/hurd/getpriority.c [TASK_SCHED_TIMESHARE_INFO]: Find `base_priority' in PIP->timeshare_base_info instead of PIP->taskinfo. * sysdeps/mach/hurd/dl-sysdep.c [FMH]: Define for i386 only. (fmh, unfmh): Define these functions only #if FMH. Otherwise define them as no-op macros. [FMH] (ELF_MACHINE_USER_ADDRESS_MASK): Redefine it to zero. (__mmap): Uncomment uses of ELF_MACHINE_USER_ADDRESS_MASK. * sysdeps/powerpc/dl-machine.h (ELF_MACHINE_USER_ADDRESS_MASK): New macro.
