	in terms of getwd.
	* du.c (main): Call getcwd with path_max as an arg.

	* install.c (change_attributes): Do chown before chmod, so
	chown doesn't remove set[ug]id bits.

	too dumb to allow -c and -o together.  Copy the source files.
	* system.h: Moved from src to lib to avoid having to add yet
	more -I options to CFLAGS.

	* du.c, ls.c: If POSIX_ME_HARDER is set in environment, use
	512-byte blocks by default.

	* eaccess.c: Support POSIX method of getting multiple groups.

	* xmalloc.c (xmalloc, xrealloc): Exit with value 2 on error,

	* Replace lib/Makefile with lib/Makefile.in.
	* configure: For some library functions that might be missing,

	Add notice to top of generated Makefile saying that it's
	automatically generated.

Thu Jun 13 00:50:18 1991  David J. MacKenzie  (djm at geech.gnu.ai.mit.edu)

	Use , instead of / as sed substitution separator so variables'
	values can contain slashes.

	foiling the test -n "`command 2>&1`" method.
	Remove makefile on signal.

	* system.h: Include sys/param.h if not _POSIX_SOURCE instead
	of if not POSIX, to get DEV_BSIZE.

	* makepath.c, posixtime.y, system.h: Add _AIX case to alloca decl.

Thu May 16 23:12:01 1991  David J. MacKenzie  (djm at albert.gnu.ai.mit.edu)

	* cp.c, mv.c, ln.c: Use alloca and strcpy directly instead of
	in a macro for generating backup filename.  The latter
	sometimes coredumps for some reason.

Sat Apr 20 00:03:09 1991  David J. MacKenzie  (djm at geech.gnu.ai.mit.edu)

	* dd.c: Add conv=notrunc and truncate output file by default,

	* Many programs: Don't bother to get the long-option index
	value from getopt_long, since we ignore it.

	args with `=' instead of ` ' in usage messages.

	* touch.c (touch): Don't refuse to touch non-regular files.

	* mv.c (copy): Try to preserve file ownership in
	cross-filesystem copies.

	* backupfile.c, rm.c: Go back to using d_ino instead of
	d_fileno.  POSIX.1 specifies neither, and d_ino is more

	conflict with standard header files.

	* cp.c (copy_reg): Instead of using NO_SPARSE_FILES, use
	st_blocks to determine whether the original file contains any
	sparse blocks, and only create them if so.  On systems without
	st_blocks, to be safe, never create sparse blocks.

Thu Nov  8 12:16:27 1990  David J. MacKenzie  (djm at apple-gunkies)

	* idcache.c: If _POSIX_SOURCE not defined, declare getpw and

	* install.c (change_attributes): Don't ignore EPERM for chown,

	* Version 1.4.

	* cp.h: Declare free returning void, not int, so it

	* dd.c (copy): Swap input bytes instead of output bytes.
	(swab_array): New function.

	* dd.c (copy): If sync and noerror, zero the buffer before the
	read instead of after so that any data read before an error
	occurred are preserved.
	On read error, print stats and seek past the bad block if noerror.
	noerror doesn't affect write errors, for POSIX.

	other than 512 or 1024 bytes.

	* du.c (main): Exit with status 0 normally.

	* ln.c (do_link): Take out code to give an error if source and
	dest are the same file.  The dubious usefulness of the special
	case to prevent 'ln x x' from removing 'x' (ln -i can be used

	if continuing after finding circular inode.
	(xrealloc): New function.

Sat Jun 16 01:45:42 1990  David J. MacKenzie  (djm at albert.ai.mit.edu)

	0 (as on pipe reads on some systems), use BSIZE instead.

	control whether st_blksize and st_blocks are used.
	* Makefile, system.h, backupfile.c: Use DIRENT to control
	whether <dirent.h> is used.

Thu May 31 00:55:36 1990  David J. MacKenzie  (djm at apple-gunkies)

	* fileblocks.c: New file.
	* du.c (blocks_to_kb): Replace with convert_blocks macro.
	(main): Recognize new -k option.
	(usage): Document it.

	[USG && !hpux]: Define GETGROUPS_MISSING.
	mv.c (rename): Put in #ifdef RENAME_MISSING not #ifdef USG.
	(do_move): Use FCHMOD_MISSING to decide whether to use fchmod().
	[USG && !hpux]: Define FCHMOD_MISSING and RENAME_MISSING.

	* mv.c (movefile): Remove trailing slashes from FROM (some
	filename completion systems add them for dirs, and they cause
	the rename syscall to fail).

Thu Feb  8 22:50:12 1990  Torbj|rn Granlund  (tege at sics.se)

	* cp.c (copy_reg): Change error handling after lseek, since
	  this is a fatal error.  Also change error message to
	  something more generally understood.
	* Handle files that end in a zero block on USG systems.

	* cp-aux.c (error): Use FATAL to recog fatal errs.

	* ln.c: Remove incorrect comment.

	* cp.c, cp-aux.c (usage): Change +dereference option to
	+no-dereference, since dereferencing is done by default and
	the option turns it off.
