2001-12-18 Jakub Jelinek <jakub@redhat.com> * sysdeps/unix/sysv/linux/sparc/sparc64/clone.S (clone): Subtract stack bias from child stack pointer before passing it to clone syscall. 2001-12-18 Ulrich Drepper <drepper@redhat.com> * sysdeps/posix/sysconf.c (__sysconf): Respect POSIX minimum for _SC_TZNAME_MAX. * sysdeps/generic/sysconf.c (__sysconf): Likewise. Reported by Thorsten Kukuk <kukuk@suse.de>. * sysdeps/unix/grantpt.c (grantpt): Correct typo in comment and add some casts. * sysdeps/unix/sysv/linux/grantpt.c: Make __unix_grantpt static. 2001-12-18 Thorsten Kukuk <kukuk@suse.de> * sysdeps/unix/sysv/linux/grantpt.c: Make errno results standard conforming: return EBADF if file descriptor is invalid and EINVAL if file descriptor is no valid tty. * login/tst-grantpt.c: New file. * login/Makefile (tests): Add tst-grantpt.
