	* 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.
	* wcsmbs/wcstold.c: Likewise.

	* sysdeps/libm-ieee754/s_nan.c: Use strtod is parameter is not empty
	string.
	* sysdeps/libm-ieee754/s_nanf.c: Likewise.
	* sysdeps/libm-ieee754/s_nanld.c: Likewise.

	* sysdeps/m68k/fpu/e_atan2.c: Use __signbit inline.
	* sysdeps/m68k/fpu/e_pow.c: Likewise.  Write 0.0/0.0 for NaN.  Fix
	typo in test for `y = 0.5'.

	* sysdeps/m68k/fpu/__math.h: Define __trunc, __signbit,
	__nearbyint.  Remove __modf.

	* sysdeps/m68k/Makefile (CFLAGS-s_copysignl.c) [$(subdir)=math]:
	Define for gcc bug workaround.

	* math/libm-test.c (log2_test): Add epsilon for long double to
	"log2 (e)" and "log2 (16)".
	(modf_test): Fix test name.
	(sqrt_test): Add missing FUNC.

[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
in glibc are duplicated in libgcc.''
[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.
