Update.
1999-06-09 Ulrich Drepper <drepper@cygnus.com> * pwd/fgetpwent_r.c: Set errno in the correct way. * shadow/fgetspent_r.c: Likewise. * pwd/fgetpwent.c: Handle long lines correctly. Little optimizations. Free static buffer when debugging memory handling. * shadow/fgetspent.c: Likewise. * grp/fgetgrent.c: Little optimization in loop. 1999-06-09 Andreas Jaeger <aj@arthur.rhein-neckar.de> * grp/tst_fgetgrent.c (write_group): Fix generation of long line in a different way.
