Thu Jan 23 04:06:42 1997 Ulrich Drepper <drepper@cygnus.com> * Make-dist (.PHONY: dist): Remove duplicate declaration. (README): Depend on version.h not version.c. * Makefile (README): Depend on version.h not version.c. * Makeconfig (inst_libdir, inst_slibdir, inst_includedir, inst_datadir, inst_zonedir, inst_localedir, inst_i18ndir, inst_bindir, inst_sbindir, inst_infodir, inst_sysconfdir): New variables. Same as variable withough inst_ but prepended with $(install_root). (localtime-time): Use $(inst_sysconfdir) not $(sysconfdir). * Makefile (install-others): Use $(inst_includedir). (gnu/stabs.h, gnu/lib-names.h): Use $(inst_includedir). * Makerules (tons of install rules): Use inst_% variables. * elf/Makefile: Likewise. * hurd/Makefile: Likewise. * intl/Makefile: Likewise. * manual/Makefile: Likewise. * po/Makefile: Likewise. * sunrpc/Makefile: Likewise. * sysdeps/mach/hurd/Makefile: Likewise. * sysdeps/standalone/i386/force_cpu386/Makefile: Likewise. * time/Makefile: Likewise. * config.make.in: Revert patch from Sat Jan 18 22:15:26 1997, leave install_root in place. * gnu-versions.h (_GNU_GETOPT_INTERFACE_VERSION): Define to 2. * posix/getopt.c (GETOPT_INTERFACE_VERSION): Define to 2. * posix/getopt1.c (GETOPT_INTERFACE_VERSION): Define to 2. * elf/Makefile [yes==$(has-ldconfig)]: Correct dependencies of ldconfig. (CFLAGS-dl-load.c): New variable, avoid gcc warning. * sysdeps/mach/hurd/configure.in: Add _LIBC_REENTRENT to DEFINES. * sysdeps/mach/hurd/getdents.c: Update copyright. De-ANSI-declfy. * sysdeps/stub/getdents.c: Likewise. Correct return value. * sysdeps/unix/getdents.c: Likewise. * sysdeps/unix/sysv/getdents.c: Likewise. * sysdeps/unix/readdir.c: Update copyright. * sysdeps/unix/bsd/sony/newsos4/Makefile: Correct ifeq arguments. * sysdeps/unix/bsd/sun/sunos4/Makefile: Likewise. * sysdeps/unix/sysv/Makefile: Likewise. * sysdeps/unix/sysv/linux/Makefile: Likewise. * sysdeps/unix/sysv/linux/alpha/Makefile: Likewise. * sysdeps/unix/sysv/linux/i386/Makefile: Likewise. * sysdeps/unix/sysv/linux/Dist: Don't distribute kernel_termios.h, but sys/kernel_termios.h. * sysdeps/unix/sysv/linux/alpha/Dist: Likewise. * sysdeps/unix/sysv/linux/Makefile [$(subdir)==termios] (sysdep_headers): Add sys/kernel_termios.h. * sysdeps/unix/sysv/linux/kernel_termios.h: Moved to... * sysdeps/unix/sysv/linux/sys/kernel_termios.h: ...here. * sysdeps/unix/sysv/linux/sys/tcgetattr.c: Use __kernel_termios and __KERNEL_NCCS instead of kernel_termios and KERNEL_NCCS resp. * sysdeps/unix/sysv/linux/alpha/ioctls.h: New file. * sysdeps/unix/sysv/linux/getdents.c: Correct problems with alignment. * sysdeps/unix/sysv/linux/alpha/syscalls.list: Remove getdents. Reported by Eirik Fuller <eirik@netcom.com>. * time/Banner: Removed. Wrong and unnecessary information. It's now in... * time/README: New file. * time/Makefile (distribute): Remove Banner, add README. Wed Jan 22 13:19:56 1997 Richard Henderson <rth@tamu.edu> * sysdeps/unix/sysv/linux/alpha/ioperm.c (platforms): Add Sable. (init_iosys): Recognize /etc/alpha_systype as a four-tuple for the purpose of supporting brand new systems. (*): The type of iosys variables should be iosys_t. 1997-01-22 Paul Eggert <eggert@twinsun.com> * strftime.c (_strftime_copytm): New function, to work around Solaris 2.5 tzset bug. Wed Jan 22 23:05:14 1997 Ulrich Drepper <drepper@cygnus.com> * sysdeps/mach/hurd/vdprintf.c: Complete de-ANSI-declfication. * sysdeps/posix/pipestream.c (writedecl): Fix typo. Reported by Marcus G.

Although the Corrigendum 1 describes the result as implemented the even more recent Amendement 1 seconds the position of ISO C:1990 where the %n directive has no effect on the assignment count. * stdio-common/bug10.c: Likewise. * stdio-common/scanf1.c: Likewise. * stdio-common/scanf3.c: Likewise. * stdio-common/scanf10.c: Likewise. * stdio-common/tstdiomisc.c: Likewise. * new-malloc/obstack.h: Don't define malloc using bcopy if malloc is not available. This leads to problems since bcopy does not return a value. Instead define _obstack_memcpy based on memcpy or bcopy. This name isn't used outside obstack.h and so no problems from using the memcpy function in a file including obstack.h can result. Reported by Martin Trapp <trapp@ipd.info.uni-karlsruhe.de>. Tue Jan 21 18:35:55 1997 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * misc/regexp.h (compile): Fix typos. Tue Jan 21 01:01:59 1997 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/unix/sysv/linux/sys/procfs.h (struct elf_prpsinfo): Fix type of pr_{pid,ppid,pgrp,sid} fields. * sysdeps/unix/sysv/linux/alpha/sys/procfs.h (struct elf_prpsinfo): Likewise.

+ /* We have a severe problem here. The ISO C standard
+ contradicts itself in explaining the effect of the %n
+ format in `scanf'. While in ISO C:1990 and the ISO C
+ Amendement 1:1995 the result is described as
+
+ Execution of a %n directive does not effect the
+ assignment count returned at the completion of
+ execution of the f(w)scanf function.
+
+ in ISO C Corrigendum 1:1994 the following was added:
+
+ Subclause 7.9.6.2
+ Add the following fourth example:
+ In:
+ #include <stdio.h>
+ int d1, d2, n1, n2, i;
+ i = sscanf("123", "%d%n%n%d", &d1, &n1, &n2, &d2);
+ the value 123 is assigned to d1 and the value3 to n1.
+ Because %n can never get an input failure the value
+ of 3 is also assigned to n2. The value of d2 is not
+ affected. The value 3 is assigned to i.
+
+ We go for now with the historically correct code fro ISO C,
+ i.e., we don't count the %n assignments. When it ever
+ should proof to be wrong just remove the #ifdef above. */
