Thu May 30 11:24:05 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> cvs/libc-960602 cvs/libc-960601 cvs/libc-960531

	* po/header.pot: Replace with exact boilerplate pinard dictates.

	* sysdeps/i386/strtok.S (Lillegal_argument): Remove this code to set
	errno and the check that jumped to it.

	* sysdeps/mach/hurd/Makefile (errnos.d): Use $(sed-remove-objpfx).

Thu May 30 03:21:57 1996  Ulrich Drepper  <drepper@cygnus.com>

	* FAQ: Document need of gperf program for developers.

	* elf/elf.h: Fix typos in comments.

	* libio/stdio.h [!__STRICT_ANSI__ || _POSIX_SOURCE]: Add
        prototypes for `ctermid' and `cuserid'.

	* locale/programs/locale.c: Switch to user selected locale
	before printing variables.

	* math/Makefile [$(long-double-fcts)==yes]: Define long-m-routines
        and long-c-routines.  Only if the `long double' data type is
        available we need to compile the functions.
	(libm-routines): Add $(long-m-routines).
	(routines): Remove isinfl, isnanl.  Use new file s_isinfl and
	s_isnanl instead if `long double' is available.

	* math/math.h: Include <mathcalls.h> again to define `long double'
        functions.

	* math/math_private.h: Define data types, prototypes and access
        macros for `long double'.

	* stdlib/stdlib.h: Add prototypes for `strtoll' and `strtoull'.
	[GCC2 && OPTIMIZE]: Define strto{,u}ll as inline function which
	calls __strto{,u}q_internal.

	* stdlib/strfmon.c: Replace PTR by `void *'.

	* stdlib/strtoq.c: Define strtoll as weak alias.
	* stdlib/strtouq.c: Define strtoull as weak alias.

	* string/tester.c: Correct `strsep' test.

	* sysdeps/generic/strsep.c: Make compatible with BSD version.
        Trailing characters of skip set are not skipped.  In this case
        empty tokens are returned.

	* sysdeps/i386/isinfl.c, sysdeps/i386/isnanl.c,
        sysdeps/ieee754/isinf.c, sysdeps/ieee754/isinfl.c,
        sysdeps/ieee754/isnan.c, sysdeps/ieee754/isnanl.c: Removed.  We
        now use the versions part of libm.

	* sysdeps/i386/strsep.S: Removed.  Generic C version is of
	similar speed.
	* sysdeps/i386/strtok.S: Remove support for `strsep'.

	* sysdeps/libm-i387/e_acosl.S, sysdeps/libm-i387/s_ceill.S,
        sysdeps/libm-i387/s_copysignl.S, sysdeps/libm-i387/s_finitel.S,
        sysdeps/libm-i387/s_floorl.S, sysdeps/libm-i387/s_isinfl.c,
        sysdeps/libm-i387/s_isnanl.c, sysdeps/libm-i387/s_nextafterl.c,
        sysdeps/libm-i387/s_rintl.S, sysdeps/libm-i387/s_significandl.S:
        New i387 specific math functions implementing `long double'
        versions.

	* sysdeps/libm-ieee754/s_ceill.c,
        sysdeps/libm-ieee754/s_copysignl.c,
        sysdeps/libm-ieee754/s_fabsl.c, sysdeps/libm-ieee754/s_finitel.c,
        sysdeps/libm-ieee754/s_floorl.c, sysdeps/libm-ieee754/s_isinfl.c,
        sysdeps/libm-ieee754/s_isnanl.c,
        sysdeps/libm-ieee754/s_nextafterl.c,
        sysdeps/libm-ieee754/s_rintl.c, sysdeps/libm-ieee754/s_scalbnl.c,
        sysdeps/libm-ieee754/s_significandl.c: New generic `long double'
        versions of libm functions.

	* sysdeps/libm-i387/e_exp.S: Add a few comments to explain the
        Intel FPU nonsense.

	* sysdeps/libm-i387/s_ceil.S, sysdeps/libm-i387/s_ceilf.S,
        sysdeps/libm-i387/s_floor.S, sysdeps/libm-i387/s_floorf.S: Correct
        handling of local variables.  The old version created a stack
        frame but stored the values outside.

	* sysdeps/libm-ieee754/s_isinf.c, sysdeps/libm-ieee754/s_isnan.c
        [!NO_LONG_DOUBLE]: Define alias with `long double' versions name.

	* login/pututline_r.c: Include sys/stat.h.  Fix typos.

        according to currently used locale for category LC_CTYPE by
	inet_nsap_ntoa.  Now in <arpa/inet.h>.
        _IO_dup2 to contain complete parameter list.
