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.
