* inet/netdb.h: Moved to resolv. * inet/Makefile (headers): Remove netdb.h. * resolv/Makefile (headers): Add netdb.h. * resolv/gethnamaddr.c, resolv/inet_addr.c, resolv/netdb.h, resolv/res_send.c: Updated from BIND-4.9.3-BETA26. * hurd/thread-cancel.c: If SS->cancel_hook is not null, call it before resuming the thread. * hurd/hurd/signal.h (struct hurd_sigstate): New member `cancel_hook'. * hurd/Makefile: Removed dep on hurd/signal.h for RPC stub objects. Mon Aug 21 16:37:09 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu> * sysdeps/i386/dl-machine.h (elf_machine_rel): Grok R_386_NONE relocs, and do nothing. Why the linker generates them we may never know. * sysdeps/mach/hurd/i386/intr-msg.h: New file.
