2018-10-16  Stuart Caie <kyzer@cabextract.org.uk>

	* src/cabinfo.c: thanks to Micah Snyder for sending some very corrupt
	files, where cabinet blocks can be found absolutely anywhere, not in
	a continguous sequence after the file entries, I found cabinfo unfit
	for purpose. I've updated it with a new output format, where the
	blocks for a folder appear immediately after each folder, rather than
	all at the end.

2018-10-16  Stuart Caie <kyzer@cabextract.org.uk>

	* src/cabextract.c: use libmspack's new MSCABD_PARAM_SALVAGE mode
	for cabextract -f, to allow extracting even more data from broken
	cabinet files.

2018-07-31  Stuart Caie <kyzer@cabextract.org.uk>

	* configure.ac: drop AC_FUNC_MKTIME. Looking into it, even C89 has
	a mktime() function, the configure test is mostly checking if it
	is POSIX-conformant or not, and substitutes mktime.c if not. But
	even the replacement has no TZ handling, so it seems OK to me to
	accept the system mktime() in any case. The fnmatch() and getopt()
	substitutions remain because they enable GNU extensions that
	cabextract uses (FNM_CASEFOLD and getopt_long() respectively).
	Thanks to Stefan Haubenthal for bringing up the issue.

2018-07-28  Stuart Caie <kyzer@cabextract.org.uk>

	* src/cabinfo.c: cabinfo now supports examining more than one file

2018-07-17  Stuart Caie <kyzer@cabextract.org.uk>

	* amibuild.sh: support using setlocale()/iconv() in the OS4 version.

	* amibuild.sh: build the 68K version with -noixemul so the resulting
	executable doesn't need ixemul.library, libnix is used instead.
	Because libnix has no umask(), add a HAVE_UMASK feature test.

	* src/cabextract.c: add a new feature flag, LATIN1_FILENAMES,
	which should be defined if the host environment expects ISO-8859-1
	filenames rather than UTF-8. This adds in a step to translate
	even UTF-8 filenames to ISO-8859-1.  It's only enabled for the
	Amiga build so far.

2018-03-07  Stuart Caie <kyzer@cabextract.org.uk>

	* configure.ac, src/cabextract.c: add support for choosing the
	character encoding of non-UTF8 filenames, using the iconv library.
	This is based on a patch originally developed by Kevin Tardif.

	* src/cabextract.c: try setting various UTF8 locales for LC_CTYPE,
	in order to get tolower() / towlower() to lowercase non-ASCII
	characters.  Again, thanks to Kevin Tardif for discussing this
	and supplying a proposed patch.

2016-04-16  Stuart Caie <kyzer@cabextract.org.uk>

	* configure.ac: change my email address to kyzer@cabextract.org.uk

2015-05-10  Stuart Caie <kyzer@4u.net>

	* wince_rename, wince_info: allow the possibility that strings have
	more than one null byte. Thanks to Stefan Riegler for the suggestion.

2015-05-10  Stuart Caie <kyzer@4u.net>

	* Makefile.am: Add subdir-objects option as suggested by autoreconf.

	* configure.ac: Add AM_PROG_AR as suggested by autoreconf.

2015-02-25  Stuart Caie <kyzer@4u.net>

	* create_output_name(): Simplify code; do path checking only after
	output name has been constructed. Use towlower to lowercase UTF-8
	characters. Remove both leading '/' and '\' from cab filenames and
	change both "../" and "..\" to "xx", for Cygwin and other Cygwin-like
	environments that use both '/' and '\' as path separators. Thanks to
	Alexander Cherepanov and the MITRE team.

2015-02-18  Stuart Caie <kyzer@4u.net>

	* create_output_name(): the check against leading slashes could be
	evaded with malformed UTF-8. Thanks to Alexander Cherepanov for
	reporting the issue.

2015-01-18  Stuart Caie <kyzer@4u.net>

	* wince_rename: installed files now include their install directories.
	Thanks to Alfonso Acosta for sending a patch.

2015-01-08  Stuart Caie <kyzer@4u.net>

	* create_output_name: avoid invalid memory reads because of invalid
	UTF-8 encodings. Use the Unicode substitution character for most
	bad UTF-8 or Unicode encodings. Thanks to Hanno Böck.

	* src/cabinfo.c: stop trying to convert UTF-8 to ASCII in filename.
	Instead, prepend "UTF: " and print it to the terminal verbatim.

2011-07-19  Stuart Caie <kyzer@4u.net>

	* doc/ja/cabextract.1: Katsumi Saito updated the Japanese translation
	of cabextract's manpage to include the -t option. Thanks again!

2011-05-11  Stuart Caie <kyzer@4u.net>

	* src/cabinfo.c: changed the largefile detection header to the same
	as mspack/system.h

2011-04-27  Stuart Caie <kyzer@4u.net>

	* src/cabextract.c: changed char* to const char* in line with changes
	in libmspack. See mspack/ChangeLog for more details.

2011-04-25  Stuart Caie <kyzer@4u.net>

	* load_spanning_cabinets(): Print the error code caused by a failed
	cabinet merge, before ruining the error code by calling cabd->close().
	Thanks to Drew D'Addesio for reporting the problem.

2011-01-19  Stuart Caie <kyzer@4u.net>

	* doc/wince_cab_format.html: Identified a new file flag in the WinCE
	header file. Thanks to Paul Sokolovsky for asking me to look into it.

2010-07-19  Stuart Caie <kyzer@4u.net>

	* mspack: MS-ZIP recovery now recovers more bytes. Also, when a file
	fails to unpack because of a read error during decompression, all
	subsequent files in the same folder will give the same error, instead
	of claiming to be OK. See mspack/ChangeLog for full details.

2010-07-17  Stuart Caie <kyzer@4u.net>

	* src/cabsplit: added new program, cabsplit, which splits cabinet
	files into one cabinet file per folder. Useful for debugging.

2010-06-17  Stuart Caie  <kyzer@4u.net>

	* configure.ac: Added --external-libmspack option, which allows
	you to use the libmspack library installed on your system rather
	than the copy bundled with cabextract. Thanks to Patrice Dumas
	for the patch.

2010-06-10  Stuart Caie  <kyzer@4u.net>

	* mspack: bugs in MS-ZIP and Quantum decoders have been fixed. See
	mspack/ChangeLog for full details.

2010-05-06  Stuart Caie  <kyzer@4u.net>

	* configure.ac, cabextract.c: added support for the one-arg mkdir()
	found in the MinGW32 environment. Thanks to Kevin O'Rourke for
	reporting this.
	
2009-09-24  Stuart Caie   <kyzer@4u.net>

	*  doc/wince_cab_format.html, src/wince_info, src/wince_rename:
	The files in Windows CE cabinets are numbered after the first
	ID in the FILES section, rather than what I termed the "real ID".
	Fixed the documentation and the wince tools to match. The purpose
	of the field previously called "real ID" is now unknown. Thanks
	to Marco Schindler for discovering this.

2007-08-07  Stuart Caie   <kyzer@4u.net>

	* all: cabextract and libmspack have moved to the domain
	www.cabextract.org.uk. Updated the documentation to reflect this.
	
2007-01-20  Stuart Caie   <kyzer@4u.net>

	* create_output_name(): add UTF-8 support for 6-byte characters.
	Apparently they go that far these days.

2007-01-20  Stuart Caie   <kyzer@4u.net>

	* doc/wince_cab_format.html, src/wince_info: The REGKEYS "unknown"
	flag appears to be a boolean indicating whether variable
	substitution should take place. Thanks to Dominique Gallot for
	discovering it.

2006-06-21  Stuart Caie   <kyzer@4u.net>

	* create_output_name(): add UTF-8 support for 4-byte characters.

2006-03-01  Stuart Caie   <kyzer@4u.net>

	* process_cabinets(): on the advice of Mike Mohr, cabextract no
	longer skips entire cabinets, when create_output_filename()
	returns NULL, it only skips the affected files now.

2005-10-30  Stuart Caie   <kyzer@4u.net>

	* src/cabextract.c: added test mode to cabextract, wherein files
	aren't extracted, only passed through an MD5 checksum generator.
	cabextract then lists which files passed and which files failed.

	* process_cabinets(): fixed the problem where filters don't match
	when -d option is also used. The filters match on the full
	output-file path, including the -d directory specified. We now
	trim this off before matching.
	
2005-10-29  Stuart Caie   <kyzer@4u.net>

	* fnmatch.c, getopt.c: finally resolved problems with all the GNU
	replacement functions. Obtained new versions of fnmatch and
	getopt, removing the need for alloca.c, coded out the requirement
	for mempcpy in getopt.c (I don't think it was needed anyway, but
	just to be sure I changed it to use just memcpy). Tested on Mac OS X
	(both native and using fink), Solaris 8 and Cygwin as well as Debian.

	* configure.ac: Removed the AC_FUNC_ALLOCA and
	AC_REPLACE_FUNCS([mempcpy])
	
2005-07-05  Stuart Caie   <kyzer@4u.net>

	* src/cabinfo.c: This can now search and print accurate output for
	cabinets (and files containing cabinets) over 2GB.

2005-04-21  Stuart Caie   <kyzer@4u.net>

	* src/cabinfo.c: This now prints if the NAME_IS_UTF flag is set for
	each file.

2004-10-19  Stuart Caie   <kyzer@4u.net>

	* create_output_name(): fixed out-by-one error in UTF-8 decoder. All
	UTF-8 filenames would reach the "error in UTF-8 decode" section,
	because the test for that section was "pointer >= last_character",
	not "pointer > last_character".

2004-10-18  Stuart Caie   <kyzer@4u.net>

	* process_cabinet(): now accepts that failure of create_output_name()
	is an error, and also lets that function print an error message
	rather than printing one itself.

	* create_output_name(): improved the two error messages that could
	be printed.

2004-10-15  Stuart Caie   <kyzer@4u.net>

	* create_output_name(): removes leading "./" and "../" as well as
	leading slashes from the input filename. Thanks to David Banz for
	pointing this out, as well as http://www.securityfocus.com/bid/11376/
	
2004-07-16  Stuart Caie   <kyzer@4u.net>

	* Makefile.am: added -DMSPACK_NO_DEFAULT_SYSTEM. Why wasn't this in
	earlier?

	* src/cabextract.c: added prototypes of the cabx_ functions,
	removed the prototype of cabextract_system and moved the real
	cabextract_system to before main(). This is so AIX doesn't fail on
	seeing an extern and a static definition of the same
	global. That's messed up!

	* alloca.c, fnmatch*, getopt*, mempcpy.c: imported these from
	gcc's latest libiberty. This should fix problems with Cygwin.
	
2004-03-18  Stuart Caie   <kyzer@4u.net>

	* process_cabinet(): added missing printf argument when errors on
	extracting to stdout occur. Thanks to Moritz Barsnick for finding
	it.

2004-03-08  Stuart Caie   <kyzer@4u.net>

	* all: tidy-ups for 1.0 release
	
2003-09-04  Stuart Caie   <kyzer@4u.net>

	* set_date_and_perm(): implemented the utimes() alternative to
	utime().

	* set_date_and_perm(): sets the date before the permissions are set,
	in case read-only files really do get -r--r--r-- permissions and
	your dumb OS won't let the date can't be changed.

2003-08-14  Stuart Caie   <kyzer@4u.net>

	* wince_cab_format.html: Shaun Jackman worked out six more fields
	in the header.

2003-08-12  Stuart Caie   <kyzer@4u.net>

	* cabextract.c: rewrote all function documentation in javadoc /
	doxygen format.

	* configure.ac: added AC_FUNC_ALLOCA / @ALLOCA@ / alloca.c because
	I noticed that fnmatch.c uses alloca().

2003-08-11  Stuart Caie   <kyzer@4u.net>

	* main(): Removed the redundant args.list with args.view. I was
	wondering why cabextract -l file.cab was trying to extract instead
	of list...

2003-08-06  Stuart Caie   <kyzer@4u.net>

	* configure.in, Makefile.am: rewrote the configure and build
	scripts, in the new style. fnmatch sources are now bundled, and
	now all the support code and tools are in the top directory,
	leaving src/ with nothing but cabextract code in it.

2003-08-05  Stuart Caie   <kyzer@4u.net>

	* wince_cab_format.html: converted the WinCE CAB format document
	from text to HTML.

2003-07-29  Stuart Caie   <kyzer@4u.net>

	* cabextract.c: now rewritten to use libmspack.

	* process_cabinet(): the cabinet listing now has space for 10
	digits in the size field, for those really big compressed files.
	The maximum size of a file is 4294967295 bytes.
	
2003-07-18  Stuart Caie   <kyzer@4u.net>

	* cabextract.c: started refactoring cabextract to use the
	libmspack library. Moved everything out of cabextract.c and will
	start moving things back in as necessary.

	* doc, mspack: added a doc directory, where fun things like manual
	pages, magic files and file format documents go. Made a directory for
	libmspack files.

2003-06-07  Stuart Caie   <kyzer@4u.net>

	* mspack: started creation of the libmspack library, based on the
	cabextract code. See http://www.kyz.uklinux.net/libmspack/ for more
	details about the library.

2003-05-14  Stuart Caie   <kyzer@4u.net>

	* magic.cabinet: fixed errors in CAB magic definition

	* magic.wince: added magic file entry for WinCE install format

	* configure.in: added large file support

2003-04-21  Stuart Caie   <kyzer@4u.net>

	* ja/cabextract.1: Katsumi Saito kindly translated the updated
	manual page into Japanese for me.

2003-04-20  Stuart Caie   <kyzer@4u.net>

	* cabextract.1: finally decided on feature set for cabextract 0.7,
	so I updated the manual to reflect that.
	
2003-03-12  Stuart Caie   <kyzer@4u.net>

	* wince_cab_format.txt: reverse engineered most of the file format
	for Windows CE installation CAB header files. Windows CE uses
	normal cabinet files, but the files inside the cabinets use short
	filenames and a special binary header to specify full filenames,
	install directories, registry entries and symbolic links.  If
	anyone wants to help fill in the remaining fields, I'm all ears.
	
2002-11-19  Stuart Caie   <kyzer@4u.net>

	* cabextract.c: moved the generation of the correct unix filename
	for an extracted file out of file_open() and into the main
	process_cabinet() function (it now has a helper function called
	create_output_name()). This is to make the real filename available
	outside of file_open(). (See below)

	* file_close(): chmod() and utime() are now called on the correct
	filename :)

2002-11-13  Stuart Caie   <kyzer@4u.net>

	* unix_directory_seperators(): this is a new function added to
	determine whether the CAB file is using "wrong" UNIX-style forward
	slashes as directory seperators. Microsoft CAB files use
	MS-DOS backslashes, however the tools Cablinux and PowerArchiver
	create CABs with forward-slashes.
	
2002-09-12  Stuart Caie   <kyzer@4u.net>

	* file_cabs_in_file(): if the file itself doesn't exist, we no
	longer print "Not a Microsoft cabinet file" for not finding any
	cabinets in that file.

2002-09-08  Stuart Caie   <kyzer@4u.net>

	* cabextract.c: cabextract used to segv if an LZX or Quantum
	folder came after an MSZIP folder, because the window pointer
	would be filled in by MSZIP's state. To solve this, I took the
	window pointers and associated variables out of the state union,
	and I also started clearing the state structure on startup. I also
	removed the 'what was the old compression type / free window' code
	and replaced it with a simple 'free LZX/QTM window if it exists'
	before ZIP initialisation.

2002-09-08  Stuart Caie   <kyzer@4u.net>

	* find_cabs_in_file(): if a file begins with "ISc(", cabextract
	now prints a message about how to unpack InstallShield '.cab'
	files, which begin with this signature.
	
2002-09-08  Stuart Caie   <kyzer@4u.net>

	* cabextract.c: After seeing what some people think the command
	line syntax is for cabextract is
	(e.g. http://slashdot.org/comments.pl?sid=39401&cid=4210033) I
	have decided to be nice to people who don't read manuals, and
	refuse to extract files given on the command line if they've
	already been extracted as part of another cabinet. This does
	preclude the scenario where a file is not only part of a
	multi-part set, but has a cabinet at offset 0 and _also_ has
	embedded cabs later on. The new functionality is implemented by
	the new functions remember_cabinet() and known_cabinet(), which
	use a simple linked list. If you want the old behaviour of
	cabextract back, do "find <cabs> -exec cabextract {} \;".
	
2002-09-08  Stuart Caie   <kyzer@4u.net>

	* configure.in: Upgraded my autoconf to one that has the AC_EXEEXT
	bug fixed (look up AC_EXEEXT xSYM on the Internet :). Now it
	complains about me writing to LIBOBJS directly, so I use the macro
	AC_LIBOBJ twice to add getopt and getopt1 to LIBOBJS.

2002-08-20  Stuart Caie   <kyzer@4u.net>

	* AUTHORS, ChangeLog, NEWS, cabextract.c: fixed mis-spellings of
	Matthew Russotto's name.

	* ChangeLog: finished a half-completed changelog entry. 


2002-08-12  Stuart Caie   <kyzer@4u.net>

	* cabextract.c: now prints all errors and warnings to stderr
	rather that stdout. I finally noticed that perror() prints to
	stderr, and I want to follow suit.

2002-08-11  Stuart Caie   <kyzer@4u.net>

	* extract_file(): now prints out the correct cabinet name in error
	messages, in the case of files which are split over multiple
	cabinet files and the 2nd or later split cabinet contains the
	error.

	* QTMdecompress(): fixed the QTM decoding error - basically, Matthew
	used the bitstream reading macros from my LZX decompressor. Sadly,
	these macros can only guarantee at maximum 17 bits available in the
	bit buffer, and Quantum uses up to 19 bits. I rewrote the Quantum
	bit buffer macros to be multi-pass (and therefore slower) so they
	can get the requisite number of bits.

	* QTMinit(): after fixing the decoding bug, I noticed that files
	always failed extraction when going to a second folder. It turns out
	that I forgot to reset QTM's window_posn.

	* configure.in: added limits.h to the list of checked includes

	* cabextract.c: ULONG_BITS now defined in terms of CHAR_BIT from
	<limits.h> rather than fixed to 8 bits per char. Oddly, my system
	seems to include <linux/limits.h> rather than <limits.h>.  So, for
	people like me, I also define CHAR_BIT to be 8 if it's not already
	defined.

2002-07-29  Stuart Caie   <kyzer@4u.net>

	* cabextract.c: The Ministry of Sensible Naming dictates that 
	load_cab() be renamed find_cabs_in_file(), and lose the 'search'
	argument. Calls to load_cab() where the search argument = 0 (i.e.,
	when loading spanning cabinets) be changed to load_cab_offset(x,0).

2002-07-25  Stuart Caie  <kyzer@4u.net>

	* load_cab(): Bah! off_t is defined as a signed long int, and
	not an unsigned long int as I had previously thought. This means the
	'valid cabinet' comparisions may fail. I have fixed this by making
	these comparisons unsigned.

	* cabinfo.c: added the new search mechanism to cabinfo.

2002-07-25  Stuart Caie   <kyzer@4u.net>

	* process_cabinet(): rewrote the loading mechanism. Uses the new
	load_cab() to get a list of cabinets in the base file. Also does
	bi-directional loading of spanning cabinets.

	* load_cab(): now takes a 'search' parameter. if search=0, the old
	loading behaviour is performed, but if search=1, it now does the
	exhaustive search for all matching cabinets and tries to load
	them. If a load succeeds, it skips that section of the
	file. Therefore, all embedded cabinets are found, yet most of the
	file does not need to be searched.

	* cabinet_find_header(): removed, see above. Also, in shifting the
	search, I altered the search mechanism. It now uses a state
	machine to get around border cases, rather than the flaky 'save
	the last 20 bytes and put them at the start the next time around'.
	
	* cabinet_read_entries(): now checks the MSCF signature, as there
	is no longer a cabinet_find_header() to do this.
	
2002-07-23  Stuart Caie   <kyzer@4u.net>

	* LZXdecompress(), QTMdecompress(): On systems where the LZ window
	pointer is in "low memory", runsrc (window pointer - match offset)
	could be below address 0, which wraps around to the end of memory,
	so it appears runsrc is ahead of the LZ window, and so it does not
	need 'fixing' before the match copy. Therefore the match data is
	read from the incorrect, high address. Thanks to the NetBSD team
	for discovering this and providing the patch.

2002-07-22  Stuart Caie   <kyzer@4u.net>

	* file_close(): now honours your umask settings when extracting
	files. Thanks to the NetBSD team for the patch.
	
	* cabinet_seek(), cabinet_skip(): these now print errors if
	fseek() returns an error.
	
	* QTMdecompress(): finally! Added an implementation of the Quantum
	method which was researched and written by Matthew Russotto. Many
	thanks to him for all the hard work he did to produce this. I
	tidied up the code to be more my style (and to be quite a bit
	faster by inlining the bit buffer, H, L and C), but it's still all
	his code running.

	* find_next_cabinet_file(): this is a new function which finds the
	"next cabinet" by opening the directory it would be in and reading
	each filename case-insensitively. It also handles any such "next
	cabinets" with directory elements (delimited with MS-DOS
	backslashes).

	* process_cabinet(): now uses find_next_cabinet_file() to get the
	next cabinet file. This function also replaces the hack that gets
	any directory path which might be embedded in the base cabinet
	filename (as mentioned on the command line).

2002-07-21  Stuart Caie   <kyzer@4u.net>

	* file_close(): fixed off-by-one error in setting the extracted
	file date. Thanks to Claus Rasmussen.

2002-07-20  Stuart Caie   <kyzer@4u.net>

	* file_open(): now removes any leading slashes from the name of
	the file to be extracted. Thanks to the James Henstridge and
	David Leonard for patches.

	* ensure_filepath(): now does not try to examine the directory ""
	(i.e. no directory at all) if given an absolute path (one that
	start with a slash). Thanks to the James Henstridge for the patch.

2002-04-30  Stuart Caie   <kyzer@4u.net>

	* cabextract.spec.in: changed the fixed version number to @VERSION@

2002-04-06  Stuart Caie   <kyzer@4u.net>

	* Makefile.am, configure.in: used the guide no_getopt_long.txt
	included with the gengetopt package to add getopt_long
	configuration to cabextract. Hopefully it all works now. Thanks to
	the many people who pointed out this problem and to the many
	people who offered solutions.
	
2001-09-06  Stuart Caie   <kyzer@4u.net>
	
	* Makefile.am, configure.in: made cabextract.spec one of the auto-
	generated files. Now I can do 'make distcheck' here to build a
	distribution which can be installed using 'rpm -tb
	cabextract-0.6.tar.gz'. Thanks to Daniel Resare for the know-how.
	
2001-08-20  Stuart Caie   <kyzer@4u.net>

	* Makefile.am: added an LDADD line for cabextract's LIBOBJS
	generated by configure. This means the AC_REPLACE_FUNCS line
	should actually have an effect.

	* configure.in: Removed getopt_long and mktime from the
	AC_CHECK_FUNCS, as this is done anyway.
	
2001-08-19  Stuart Caie   <kyzer@4u.net>

	* Makefile.am, configure.in, cabextract.c: moved the GNU getopt
	sources to become an automatically added dependency if
	getopt_long() can't be found in the standard library, just like
	mktime() is handled. The getopt_long(), struct option and optarg
	and optind definitions are taken from getopt.h if possible. If
	they're not there, but getopt_long() was found with standard
	includes files, it's assumed they're defined in the standard
	include files. Otherwise, we define them ourselves.

	* cabextract.c: now gets VERSION defined from configure via
	config.h.

	* decompress(): if the 'fix' option was used, the output buffer
	would always be cleared before block decompression. A nice idea,
	but the MSZIP method likes to keep the output buffer between
	blocks. Thanks to Fernando Trias for spotting this. Stopped
	clearing the output buffer.
	
	* main(): the 'fix' variable wasn't initialised to zero, so on
	some architectures, where the stack-space allocated to the
	variable isn't cleared to zero, you always got the 'fix' option
	selected. See above for why this was bad.

	* process_cabinet(): now prints "Finished processing cabinet" when
	finished extracting, instead of just a blank line. Still prints
	blank lines for listing files.

	* Makefile.am: the manpage wasn't included in the distribution.
	Fixed and re-issued the 0.3 release.
	
2001-08-02  Stuart Caie   <kyzer@4u.net>

	* decompress(): now takes a 'fix' flag, which causes MSZIP errors
	to be ignored.

	* cabinet_get_entries(): now keeps the printable information about
	previous and next cabinet parts

	* process_cabinet(): now prints the printable information about
	the next cabinet part in a multi-part cabinet
	
	* file_open(): now prepends a given directory if wanted, and can
	make the filename lowercase if wanted.

	* main(): changed to using getopt_long to parse arguments. Added
	-L (lowercase), -d (output to directory), -f (fix corrupt cabs),
	-h (help), -q (quiet) and -v was recycled to become --version,
	when used on its own.

	* LZXdecompress(): major bug fixed; the updated R0, R1 and R2 in
	uncompressed blocks were being stored in the uncomp_state block,
	not local variables. At the end of the function, the local values
	are always written back to the uncomp_state block. So the values
	placed there by the uncompressed block header were always
	overwritten. Thanks to Pavel Turbin for providing an example of
	this.
	
	* rindex(): this is the BSD precursor of the ANSI standard
	function strrchr(). Oops! Now uses strrchr(), or rindex() if
	strrchr() isn't available.

	* cabinet_find_header(): now prints an error message if it can't
	find a header.

	* fixed includes to include both <strings.h> and <string.h> if
	they both exist, and made some signedness conversions explicit.
	This should let cabextract compile with SGI's native
	compiler. Thanks to Markus Nullmeier for the patch.
	
2001-03-04  Stuart Caie   <kyzer@4u.net>

	* main(): now prints the version of cabextract in the copyright
	line.
	
	* cabinet_find_header(): now searches any kind of file, not just
	files beginning with 'MZ' header. Also, always searches entire
	file.  This slows the search down, but increases the usefulness of
	the search overall, IMHO. Thanks to Eric Sharkey for pointing this
	out.
	
	* LZXdecompress(): fixed problem in intel decoding: E8 must not
	appear in the last 10 bytes, not the last 6 bytes... Thanks to Jae
	Jung who pointed this out to me. I didn't believe him at first,
	but he was quite right. Also thanks to Antoine Amanieux for
	providing example files affected by this.

	* process_cabinet(): now extends multipart cabinet filenames to be
	in the same directory as the base cabinet.

	* cabinet_open(): now only lowercases the filename part of a
	cabinet name, not the path part.
	
2001-03-03  Stuart Caie   <kyzer@4u.net>

	* LZXdecompress(): fixed LZX bit buffer exhaustion in where
	READ_HUFFSYM() requests more bits than the buffer actually
	contains: top-of-loop overflow check now allows for the input
	pointer to be 16 bits past the end of the buffer, but checks to
	ensure none of those 16 bits are actually used. Also increased
	decomp_state.inbuf by two bytes and clear the two bytes after
	loaded block in decompress(). Thanks to Jae Jung for pointing out
	this bug, and for providing example files which exposed the bug.

2001-02-26  Stuart Caie <kyzer@4u.net>

	* added configure script / makefile using automake.

	* file_close(): now sets the timestamp on extracted files.
