* 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.

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

similar speed.

versions of libm functions.

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.

[!NO_LONG_DOUBLE]: Define alias with `long double' versions name.
