New features with AN-2019-07-15:

This is the first localization step for the schily source consolidation. Many
programs now (hopefully) call gettext() for all strings that need localization.

-	The next step will include dgettext() calls for the libraries and the
	missing programs

-	The following step will include the extracted strings

-	The last step will include German translations and install support
	for the resulting binary message object files.

----------> Please test and report compilation problems! <---------

***** NOTE: As mentioned since 2004, frontends to the tools should *****
*****		call all programs in the "C" locale		   *****
*****		by e.g. calling: LC_ALL=C cdrecord ....		   *****
*****		unless these frontends support localized strings   *****
*****		used by the cdrtools with NLS support.		   *****

		*** WARNING        ***
		*** Need new smake ***

	*** Due to the fact that schily-tools 2014-04-03 introduced to use new macro
	*** expansions and a related bug fix in smake, you need a new smake
	*** to compile this source. If your smake is too old and aborts, ensure this
	*** by calling:

	cd ./psmake
	./MAKE-all
	cd ..
	psmake/smake
	psmake/smake install

	The new smake version mentioned above is smake-1.2.4
	The recent smake version is smake-1.3

	*** Due to the fact that schily-tools 2014-01-26 introduced
	*** optimizations for the Schily version of SunPro Make, you
	*** need at least the dmake version from 2018/01/11 with support
	*** for the "export" directive to compile with this makefile system.


	WARNING: the new version of the isoinfo program makes use of the 
		*at() series of functions that have been introduced by Sun
		in August 2001 and added to POSIX.1-2008. For older platforms,
		libschily now includes emulations for these functions but
		these emulations have not yet been tested thoroughly.
		Please report problems!

	BUG WARNING: Please never report bugs to Linux distributions as they
		usually do not forward these bug reports upstream and as the
		Linux distributions typically do not let skilled people check
		the bugs. We did not hear about a FIFO problem in star for a
		long time and since the problem that (on Linux) occurred once
		every 6000-10000 tries did not happen on Solaris after
		10 million tries, it was not known otherwise.


-	star: the compress unit test no longer fails on Cygwin because the
	gzip binary is compiled incorrectly and does not support LZW.
	The related test is now skipped.

	Thanks to Heiko Eifeldt for reporting

-	star: some new unit tests failed if the schilytools source tree has
	been installed in a directory with spaces in it's name.

	Thanks to Heiko Eifeldt for reporting

-	star: The unit tests for incremental backups include archives that
	include userid/groupid and username/groupname that may not be
	restorable on a different computer. We now ignore these ID meta 
	data when comparing the results.

	Thanks to Heiko Eifeldt for reporting

-	star: When comparing nanoseconds in time stamps, star now has a mode
	that treats time stamps as equal in case that tv_nsec % 100 == 0
	and the rest of the nano seconds is equal. This is needd on Cygwin
	since NTFS counts in 1/10 microseconds since Januar 1 1601.

	This applies to both star -diff and the "newer" check while extracting
	files.

	Thanks to Heiko Eifeldt for reporting

-	star: a new option diffopts=dnlink has been implemented to support
	filesystems that do not follow the historic UNIX model for hard links
	on directories.

	Since Cygwin usually has a linkcount of 1 on directories, you need
	to use "star -diff diffopts=!dnlink ..." if you like to diff the
	meta data from a historical UNIX filesystem.

	Thanks to Heiko Eifeldt for reporting

-	star: The incremental backup/restore tests now use 
	"star -diff diffopts=!dnlink ..." to make them work on Cygwin.

	Thanks to Heiko Eifeldt for reporting

-	star: star -c -H exustar -acl -xattr-linux .
	did cause file not found messages from the attempt to archive the
	Linux xattrs. This was caused by a change from July 2018 when trying to
	optimize directory access in (non-find) create mode. The call to read
	the Linux xattrs has now been moved to the location where in former
	times the ACL code has already been moved.

	The move is needed because there is no ACL/XATTR related function
	that is similar to openat().

-	star: A similar problem with get_xattr() did exist with star -diff

-	star: star -diff did not compare ACLs since getinfo() no longer
	includes a call to get_acl(). We now call get_xattr() and get_acl()
	in diff.c

-	star: The Solaris ACL interface now implelements lacl() / lacl_get() /
	lacl_set() to support very long pathnames with ACLs.

-	star: The Linux ACL interface now implelements lacl_get_file() /
	lacl_set_file() to support very long pathnames with ACLs on platforms
	that implement the withdrawn POSIX ACL draft.

-	star: The Linux xattr interface now implelements 
	llgetxattr() / llsetxattr() / lllistxattr() to support very long
	pathnames with Linux xattrs.

-	star: New version date

-	Bourne Shell: If OPTIND is set to a new value, the getopt() internal
	variable "_sp" is now reset to 1. This is needed in order to make sure
	that a combined option string can be parsed correctly.

-	Bourne Shell/libshedit/bsh: The TAB expander now again gives .. as a 
	result if the pattern is ..

	This is needed in order to let ..TAB result in ../ on the command
	line editor.

-	ved: When opening /dev/tty, there is a fallback to stderr, if that
	open does not succeed.

-	SunPro Make: "include" and other new directives now correctly deal with
	the "#" comment sign. This was a problem introduced with permitting
	more than one filename past "include" in 2017. That change was not
	aligned with the previous (idiosyncratic) parsers features.


-	SCCS TODO:

	-	Convert sccs.c to use -NSCCS in the back end programs instead
		of converting g-file names from the command line into s.file
		names in the frontend in order to forward s.file names to the
		backend programs. Doing it this way allows us to have the SCCS
		history files "off tree" in a separate directory tree starting
		with ".sccs/" at the "project root" directory, as the related
		code to convert path names is in libcomobj::bulkprepare().

	-	Add code to admin(1) and delta(1) to retrieve the list of
		new or modified files in order to have all important code
		for a "sccs commit" in a single program that does not need to
		deal with ARG_MAX limitations.

	-	Add code to admin(1), delta(1) and get(1) to maintain/understand
		the changeset file.

	-	Add code to libcomobj to understand the changeset file,
		which is needed in order to e.g. know the file names and file
		specific SIDs/state that correspond to a project global SID.

	-	Add code to all programs to maintain a lock (for the file
		$PROJECTHOME/.sccs/SCCS/s.changeset, that would be in the file
		$PROJECTHOME/.sccs/SCCS/z.changeset) to maintain a project
		global lock.

	-	Find/verify a complete transactional model that allows to repair
		complex changes to the set of files for a project that have
		been aborted in the middle. The current idea is to create the
		file $PROJECTHOME/.sccs/changeset with the deltas to the
		changeset during a complex update operation.

	-	Find a way to decide when to use SCCS v6 type history files.
		For the project mode, this is needed in order to prevent 
		historic SCCS implementations to believe they could modify
		files without knowing about project global locks.





-	Bourne Shell Missing features for POSIX compliance:

	- Support for $'...' quoting (this is not needed for the current
					version of POSIX but for the next POSIX
					version that will be named SUSv8).
					The development of SUSv8 will start in
					late 2016.

	We are now expecting the Bourne Shell to be fully POSIX compliant.

-	Bourne Shell further TODO list:

	-	Finish loadable builtin support.

	-	POSIX does not allow us to implement ". -h", so we will
		add a "source" builtin to be able to implement "source -h"

-	The following builtins (that are available in bsh) are still missing in
	the Bourne Shell:

	err			echo with output going to stderr
	glob			echo with '\0' instead of ' ' between args
	env			a builtin version of /usr/bin/env

	The following bsh intrinsics are still missing in the Bourne Shell:

	-			the restricted bsh has restriction features that
				are missing in the Bourne shell.

	-	source -h	read file into history but do not execute

	and probably more features not yet identified to be bsh unique.
