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>.
