Thu Aug 8 16:17:38 1996 Ulrich Drepper <drepper@cygnus.com> * pwd/getpwent.c: Define BUFLEN from NSS_BUFLEN_PASSWD. * pwd/getpwent_r.c: Likewise. * pwd/getpwnam.c: Likewise. * pwd/getpwnam_r.c: Likewise. * pwd/getpwuid.c: Likewise. * pwd/getpwuid_r.c: Likewise. * grp/getgrent.c: Define BUFLEN from NSS_BUFLEN_GROUP. * grp/getgrent_r.c: Likewise. * grp/getgrgid.c: Likewise. * grp/getgrgid_r.c: Likewise. * grp/getgrnam.c: Likewise. * pwd/fgetpwent_r.c: New file. Reentrant version of fgetpwent. * pwd/fgetpwent.c: Rewrite to use fgetpwent_r. * pwd/Makefile (routines): Add fgetpwent_r. * pwd/pwd.h: Add prototypes for __fgetpwent_r and fgetpwent_r. * grp/fgetgrent_r.c: New file. Reentrant version of fgetgrent. * grp/fgetgrent.c: Rewrite to use fgetgrent_r. * grp/Makefile (routines): Add fgetgrent_r. * grp/grp.h: Add prototypes for __fgetgrent_r and fgetgrent_r. Implement shadow password lookup functions. This is no complete shadow password suite. * shadow/Makefile: New file. * shadow/fgetspent.c: New file. * shadow/fgetspent_r.c: New file. * shadow/getspent.c: New file. * shadow/getspent_r.c: New file. * shadow/getspnam.c: New file. * shadow/getspnam_r.c: New file. * shadow/putspent.c: New file. * shadow/sgetspent.c: New file. * shadow/sgetspent_r.c: New file. * shadow/shadow.h: New file. * shadow/spwd-lookup.c: New file. * shadow/nss_files/files-spwd.c: New file. Thu Aug 8 13:33:45 1996 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/ftime.c: New file. Available system call is only a stub. Reported by Matthias Urlichs. * Makeconfig [!default_cflags]: Change default value from `-g' to `-g -O'. * configure.in: Recognize i686. * sysdeps/i386/i686/Implies: Default on i586 optimized code. Thu Aug 8 12:40:20 1996 Matthias Urlichs <smurf@smurf.noris.de> * Makeconfig [$(build-omitfp) == yes]: Add to CFLAGS-.so value of CFLAGS-.o, not CFLAGS-o. * sysdeps/unix/sysv/linux/init-first.c (init): Add volatile pointer to ourself. Otherwise `gcc -O3' optimized init away. sure that all tables in binary file are word-aligned.
