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.

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.
