* nis/nis_subr.c (nis_getnames): Revert last change.cvs/fedora-glibc-20061205T2141
2006-12-04 Jakub Jelinek <jakub@redhat.com> * sysdeps/unix/sysv/linux/ttyname.c: Include termios.h. (ttyname): Use tcgetattr instead of isatty, don't set errno to ENOTTY. * sysdeps/unix/sysv/linux/ttyname_r.c: Include termios.h. (__ttyname_r): Use tcgetattr instead of isatty, don't set errno to ENOTTY. * io/Makefile: Add rules to build and run tst-ttyname_r test. * io/tst-ttyname_r.c: New test.
