Update.

1998-02-17  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* math/libm.map: Move all symbols that are new in glibc 2.1 to
	version GLIBC_2.1.

1998-02-17  Ulrich Drepper  <drepper@cygnus.com>

	* stdio-common/vfscanf.c (inchar): Check c for being EOF before
	trying to read another character.

1998-02-05  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* nis/nss_nis/nis-alias.c (_nss_nis_getaliasbyname_r): Convert
	name to lowercase.

	* nis/nss_nis/nis-network.c (_nss_nis_getnetbyname_r): Convert
	name to lowercase, add test for big enough buffer.

1998-02-03  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* sysdeps/unix/sysv/linux/alpha/rt_sigaction.S (rt_sigreturn):
	Make compatible with older kernels. Patch by Richard Henderson.
