update from main archive 961220 Sat Dec 21 04:14:16 1996 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/common/pause.c: Add missing second argument in call to __sigpause. Reported by a sun <asun@zoology.washington.edu>. * locale/weight.h: Correct handling of collation elements. Reported by Keld Simonsen <keld@dkuug.dk>. * manual/time.texi: Document ^ flag and %P format. * new-malloc/malloc.c: Update from Wolfram Gloger. * nss/nss.h: Reformat copyright. * posix/sched.h: Likewise. * sysdeps/i386/fpu_control.h: Likewise. * sysdeps/unix/sysv/linux/fcntlbits.h: Likewise. * sysdeps/unix/sysv/linux/ioctls.h: Likewise. * sysdeps/unix/sysv/linux/sigcontext.h: Likewise. * sysdeps/unix/sysv/linux/utsnamelen.h: Likewise. * sysdeps/unix/sysv/linux/sys/acct.h: Likewise. * sysvips/sys/msg.h: Likewise. * stdio-common/Makefile (routines): Remove fcloseall. * stdio-common/fcloseall.c: Removed. * stdlib/Makefile (distribute): Add abort-instr.h. * sysdeps/generic/abort-instr.h: New file. * sysdeps/i386/abort-instr.h: New file. * sysdeps/generic/abort.c: Use lock and stage counter to prevent any form of loop. * sysdeps/unix/sysv/linux/timebits.h: Define CLK_TCK as 100. * sysdeps/unix/sysv/linux/alpha/timebits.h: Define CLOCKS_PER_SEC as 1000000. Define CLK_TCK as 1024. * time/time.c (CLK_TCK): Define only if not already set. * time/strftime.c: Don't use `isdigit' when computing field width from string since the locale might have more than one digit block.
