1997-09-16 23:48 Ulrich Drepper <drepper@cygnus.com> * libio/fileops.c: Define __set_errno if necessary. * libio/libioP.h: Don't use __BEGIN_DECLS/__END_DECLS, expand macros. 1997-09-16 22:03 Ulrich Drepper <drepper@cygnus.com> * string/Makefile (headers): Instead bits/string2.h. Reported by David S. Miller <davem@jenolan.rutgers.edu>. 1997-09-16 13:31 David S. Miller <davem@tanya.rutgers.edu> * sysdeps/unix/sysv/linux/sparc/sparc64/bits/statfs.h: New file. 1997-09-16 17:42 Ulrich Drepper <drepper@cygnus.com> * sysdeps/generic/bits/select.h (__FD_ZERO): Declare __arr variable as of type __fdset *. * sysdeps/i386/bits/select.h: Likewise. Reported by David S. Miller <davem@jenolan.rutgers.edu>. 1997-09-16 04:32 Ulrich Drepper <drepper@cygnus.com> * hesiod/hesiod.c: Don't use and define cistrcmp. We have strcasecmp. (hesiod_init): Use of HES_DOMAIN need not be protected by __secure_getenv. (hesiod_to_bind): Avoid using strcat and extra strlen calls, use stpcpy. * string/Makefile (noinl-tester-ENV): New variable to make strerror test pass. (CFLAGS-noinl-tester): Make sure we test the correct functions. * sysdeps/stub/atomicity.h: Fix typo. Zack Weinberg <zack@rabi.phys.columbia.edu> told me this twice. * manual/string.texi: Document strnlen and mempcpy. Tell a bit more about the locale dependence of strcasecmp and strncasecmp. * sysdeps/unix/sysv/linux/sparc/sparc64/syscalls.list: Remove ptrace. * sysdeps/unix/sysv/linux/sys/ptrace.h (ptrace): Change return value type to long int. * sysdeps/unix/sysv/linux/ptrace.c: Likewise. Adopt local variable types. * sysdeps/unix/sysv/linux/sparc/sparc64/longjmp.S: Fix typo. Patches by David S. Miller <davem@jenolan.rutgers.edu>.
