* sysdeps/mach/hurd/dup2.c: Fixed broken test in last change. * elf/dl-error.c (_dl_catch_error): Actually call the OPERATE function. Duh. * hurd/Makefile (distribute): Added hurdstartup.h. * hurd/hurd.h: Remove _hurd_startup decl. * hurd/hurd/ioctl.h (_HURD_HANDLE_IOCTLS): Use __attribute__ ((__unused__)) instead of gratuitous self reference. * sysdeps/mach/hurd/dup2.c: Call _hurd_alloc_fd to expand the table if FD2 doesn't fit. * sysdeps/mach/hurd/getdtsz.c: Return the RLIM_NOFILE soft limit, not the current table size. * sysdeps/i386/init-first.c: New file. * sysdeps/stub/init-first.c: New file.
