	* grp/fgetgrent.c: Don't use fixed buffer length.  Allow dynamic
	adjustment if the underlying function say it is too small.
	* pwd/fgetpwent.c: Likewise.
	* shadow/fgetspent.c: Likewise.
	* shadow/sgetspent.c: Likewise.

	* grp/fgetgrent_r.c (__fgetgrent_r): If `parse_result' returns -1
	this means there was not enough room for the gr_mem array.

	* nss/nss_files/files-XXX.c: Leave loop and return error if
	`parse_result' returns -1.

	* nss/nss_files/files-parse.c (parse_line): Return -1 if parsing
	of trailing list fails because of low memory.
	(parse_list): Rewrite.  The logic was completly incorrect since
	the checks for overflowing the array were not executed when
	needed.

	* shadow/sgetspent_r.c: Only a return value > 0 from parse_line
	signals success.

	* nss/getXXbyYY.c: Make sure NULL is returned if we ran out of memory.
	* nss/getXXent.c: Likewise.

	* stdlib/strtod.c (SET_MANTISSA): Make sure that at least one bit
	is set in mantissa.
	* stdlib/strtof.c: Likewise.
	* stdlib/strtold.c: Likewise.
	* wcsmbs/wcstof.c: Likewise.

1997-04-02 13:56  Ulrich Drepper  <drepper@cygnus.com>

1997-04-02 13:55  Ulrich Drepper  <drepper@cygnus.com>

1997-03-30 10:59  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	__nearbyint.  Remove __modf.

	* sysdeps/m68k/Makefile (CFLAGS-s_copysignl.c) [$(subdir)=math]:

+
+[A22] {UD} The problem is that the IPv6 development still has not reached
+a point where it is stable.  There are still lots of incompatible changes
+made and the libc headers have to follow.
+
+Currently (as of 970401) according to Philip Blundell <pjb27@cam.ac.uk>
+the required kernel version is 2.1.30.

+[Q23]	``When compiling GNU libc I get lots of errors saying functions

+
+[A23] {EY} This is *exactly* the same problem that I was having.  The
+problem was due to the fact that the autoconfigure didn't correctly
+detect that linker flag --no-whole-archive was supported in my linker.
+In my case it was because I had run ./configure with bogus CFLAGS, and
+the test failed.
+
+One thing that is particularly annoying about this problem is that
+once this is misdetected, running configure again won't fix it unless
+you first delete config.cache.
+
+{UD} Starting with glibc-2.0.3 there should be a better test to avoid
+some problems of this kind.  The setting of CFLAGS is checked at the
+very beginning and if it is not usable `configure' will bark.
