New features with AN-2016-06-28:

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. To ensure this, call:

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


	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!

	The new smake version mentioned above is smake-1.2.4

-	patch: implement some workarounds in our testsuite for bugs in 
	/usr/bin/patch from FreeBSD that is used in a randomized compare test
	between spatch and the local patch.  The current conclusion from this
	test ist that our spatch is the only patch implementation without
	known bugs.
	gpatch always missbehaves when fed from "diff -U0" output.
	BSDpatch always missbehaves when fed from "diff -e" output.


-	SCCS testsuite: fixed a bug in the new SCCS history format test.
	The script still used the hardcoded "joerg" even though there
	was a variable with the logname already.

-	Bourne Shell testsuite: Fixed a typo bug in a shell script. The file
	sh/tests/shelltests/error/error.sh contained a "O" instead of a "0".

-	Bourne Shell: fixed a bug introduced with the last release: "exec 5>file"
	did close fd #5 instead of keeping it open.

-	Bourne Shell testsuite: Added a test to check whether "exec 5>file"
	works together with "echo bla 1>&5".

-	Test suite control software: Added a workaround for a dash bug in "echo".
	Dash stops at null bytes and does not print them.

-	Test suite control software: Now defines a simple "seq" function in case
	that there is no such command. This is needed on OS X

-	Test suite for patch: Accept /usr/bin/awk if this is a nawk - needed 
	for OSX

-	Test suite control software: Fixed a typo that used "test x -eq y"
	where "x" could be a string instead of a number. We now use a string
	compare with "test x = y".

-	Star: star in "-dump" mode and when using the FIFO did overwrite the 
	tar header for a file with the POSIX.1-2001 extended tar header for
	efficiency. This unfortumately did overwrite data that was later 
	used by:

		star -c -dump -vv

	for the verbose listing and caused username/groupname to be "root".
	We no longer allocate the PTB from the FIFO buffer in this case and
	introduce a minor performance penalty when using "star -c -vv".

-	Star: now calling strlcpy() instead of strcpy() when copying CPIO
	file names as CPIO has no checksum and may observe rotten archives.
	Thanks to Hanno Bck for the report.

-	Star: Only check CPIO-BIN filenames for swapped bytes when the filename
	would fit into a 512 byte header. Cpio officially only support 256 bytes
	in the filename. In theory 65k is possible but with star -no-fifo,
	we only have 10k to check.
	Thanks to Hanno Bck for the report.

-	Star: Abort with CPIO-BIN archives when the symlink target name size is
	seen as a number <= 0 in the cpio header. This avoids a core dump from
	rotten CPIO archives.
	Thanks to Hanno Bck for the report.

-	Star: When using the outdated signed checksums, star could incorrectly
	assume that a block o characters that sums up to 0 is an EOF block.
	Star now defines such a block as a potential EOF block and repeats the
	the computation using unsigned chars to verify whether it really is
	an EOF block.
	Thanks to Heiko Eifeldt for the report.

-	Bourne Shell Missing features for POSIX compliance:

	- Do not list functions when calling "set" with no arguments.
	  Note that this POSIX requirement is seen as a POSIX bug as there
	  is no POSIX command to list function definitions.
	  NOTE that this will not be implemented before POSIX bug
	  http://austingroupbugs.net/view.php?id=1025 was fixed.

	- A POSIX whitepaper at: http://www.unix.org/whitepapers/shdiffs.html
	  claims that:
			IFS=o; violet

	  should not execute "vi". The normative text in the POSIX standard
	  describes the historic Bourne Shell behavior, but the rationale
	  describes the deviating behavior from "ksh".


	- Support for $'...' quoting (this is not needed for the current
					version of POSIX but for the next POSIX
					version that will be SUSv8)

	We are getting very close to full POSIX support.


-	Bourne Shell further TODO list:

	-	Try to make

		lastline=
		while read line
		do
			lastline=$line
		done < /etc/passwd
		echo "lastline=$lastline"

		print the last line of /etc/passwd without the exec "trick"
		that is documented in the man page.
	
	-	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 excute

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