Wed May 22 01:48:54 1996 Ulrich Drepper <drepper@cygnus.com>

	* stdlib/strtol.c [!QUAD] (ULONG_MAX, LONG_MAX): Define these
	macros if they are not available.
	(WEAKNAME): New macro to declare argument as weak.
	Define function with __ prefix and add normal name as weak alias.

	* sysdeps/posix/euidaccess.c (S_IROTH, S_IWOTH, S_IXOTH): Defines
	these macros if not already available based on R_OK, W_OK, and
	X_OK.

Tue May 21 18:48:46 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>

	* misc/sys/syslog.h (__need___va_list): Define this instead of
	__need_va_list before including <stdarg.h>.

	* Makerules (o-iterator): Use $(object-suffixes-left) instead
	of $(object-suffixes) to produce repetitions; this is used for other
	lists than just that one.
	[versioned]: Use $(o-iterator) properly.

	* sysdeps/unix/sysv/linux/Implies: Include `gnu'.
	* sysdeps/mach/hurd/Implies: Likewise.

Sat May 18 02:57:46 1996  Ulrich Drepper  <drepper@cygnus.com>

	* login/Makefile: New file.  This directory contains functions
	for user administration.
	* Makefile (subdirs): Add login.

	* misc/Makefile (headers): Remove utmp.h.  Now in login/utmp.h.
	(extra-libs, libutil-routines): Ditto.
	* misc/login.c, misc/login_tty.c, misc/logout.c, misc/logwtmp.c,
	misc/utmp.h: Moved to misc/.
	* login/login.c, login/login_tty.c, login/logout.c,
        login/logwtmp.c, login/utmp.h: Moved to here from misc/.

	* login/utmp.h: Split file.  Definitions of data structures
	and constants are now in the system dependent utmpbits.h file.

	* login/setutent_r.c, login/setutent.c, login/endutent_r.c,
	login/endutent.c, login/getutent_r.c, login/getutent.c,
	login/getutid_r.c, login/getutid.c, login/getutline_r.c,
	login/getutline.c, login/pututline_r.c, login/pututline.c:
	New files.  Routines to handle utmp-style files.

	* sysdeps/gnu/utmpbits.h: New file.  Contains GNU/Linux
	specific definitions of utmp data structures and constants.

	* sysdeps/unix/sysv/utmpbits.h: Renamed from sysdeps/unix/sysv/utmp.h.

	* sysdeps/generic/utmpbits.h: New file.  Generic (BSDish) version of
	definitions of utmp data structures and constants.

Fri May 17 00:01:31 1996  Ulrich Drepper  <drepper@cygnus.com>

	* locale/C-monetary.c: Default value for mon_decimal_point should be
        '.'.

	* stdio-common/printf.h: Remove Linux libc compatibility stuff.
	Add `extra' flag.  Currently used in __printf_fp.

	* stdio-common/printf_fp.c (__guess_grouping): Renamed from
        `guess_grouping' and extend visibility to extern.  This function
        is now used in `strfmon'.
	(__printf_fp): Recognize new bit flag in info struct.  This
	triggers to use the grouping information and decimal point from
	the LC_MONETARY category instead of the LC_NUMERIC category.

	* stdio-common/vfprintf.c (process_arg): Correct major bug.  In
	`complicated' loop we must not use the varargs because the args
	are already available in the ARGS_VALUE array.

	* stdlib/Makefile (headers): Add monetary.h.
	(routines): Add strfmon.
	* stdlib/monetary.h: New file.  Header for strfmon function.
	* stdlib/strfmon.c: New file.  Implement strfmon function to print
	monetary amounts according to current locale's rules.

	* sysdeps/unix/sysv/linux/i386/sys/vm86.h: The kernel header is
	now (>= Linux-1.3.100) called <asm/vm86.h>.
