* NEWS: doc: update NEWS for 2.6.3 release

2016-11-26  Explorer09 <explorer09@gmail.com>

	* configure.ac, src/Makefile.am: build: New configure option
	'--disable-bootstrap'.  If configure is run with '--disable-bootstrap', then stage1flex
	won't be built and stage1scan.c will be generated by sed'ing scan.c.  This option is intended to workaround bootstrap bugs rather than to
	fix the bootstrapping issues which are proving subtler and harder to
	fix than anyone would like.

2016-11-26  Explorer09 <explorer09@gmail.com>

	* src/Makefile.am: build: "make clean" deletes stage1scan.c,
	stage1flex

2016-11-26  Explorer09 <explorer09@gmail.com>

	* configure.ac, src/Makefile.am: build: allow building libfl even
	with --disable-libfl.  For various reasons, we may wish to build libfl explicitly even when
	configure has been run with the --disable-libfl option. This is
	possible, now, via 'make -C src libfl.la'.

2016-12-19  Alexis La Goutte <alexis.lagoutte@gmail.com>

	* src/flex.skl: scanner: remove trailing whitespace in skeleton

2016-12-01  Demi Obenour <demiobenour@gmail.com>

	* src/buf.c, src/main.c, src/parse.y: scanner: Disallow, overquote
	'[' and ']' in prefix

2016-12-29  Samuel Thibault <samuel.thibault@ens-lyon.org>

	* src/main.c: scanner: allocate correct buffer size for m4 path.  Flex did not check the length of the m4 path which could lead to a
	buffer overflow in some cases. Additionally, not all platforms
	believe in PATH_MAX, so stop relying on it.  Fixes #138

2016-11-24  Will Estes <westes575@gmail.com>

	* NEWS: doc: note no more libcompat in NEWS

2016-11-24  Will Estes <westes575@gmail.com>

	* lib/Makefile.am: build: explain empty lib/Makefile.am

2016-11-20  Explorer09 <explorer09@gmail.com>

	* configure.ac: build: warn about cross compiling with *alloc

2016-11-19  Explorer09 <explorer09@gmail.com>

	* configure.ac, lib/Makefile.am, lib/lib.c, src/Makefile.am: build:
	Link $(LIBOBJS) from src/ dir, remove libcompat.la.  The libcompat.la library was small and less friendly to
	bootstrapping and cross compilation. Now, we will simply link
	individual object files as needed, which is simpler.

2016-11-16  Explorer09 <explorer09@gmail.com>

	* src/Makefile.am: build: Let stage1flex respect LFLAGS

2016-11-14  Will Estes <westes575@gmail.com>

	* NEWS: doc: describe --disable-libfl in NEWS

2016-10-31  Explorer09 <explorer09@gmail.com>

	* configure.ac, src/Makefile.am: build: Add --disable-libfl
	configure option.  Disabling libfl is useful when building flex for a cross-toolchain.  Fixes: GH-99

2016-11-09  Demi Obenour <demiobenour@gmail.com>

	* src/flex.skl, tests/array_r.l: fix backwards incompatible changes
	in 2.6.2.  This patch addscompatibility `#defines` for all macros affected by
	`%prefix`.  Fixes #113.

2016-11-08  Will Estes <westes575@gmail.com>

	* tests/.gitignore: git: ignore quote_in_comment artifacts

2016-11-08  Demi Obenour <demiobenour@gmail.com>

	* src/scan.l, tests/Makefile.am, tests/quote_in_comment.l,
	tests/quote_in_comment.txt: Fixes a major bug in Flex's own lexing
	of literals.  My changes caused Flex to mishandle string and character literals in
	line comments.  This commit fixes them.  Fixes #113.

2016-11-06  Thomas Klausner <wiz@NetBSD.org>

	* configure.ac: Fix unportable test(1) operator.  "==" is only supported by bash, "=" is the standard comparison
	operator.

2016-11-02  Demi Obenour <demiobenour@gmail.com>

	* tests/quotes.l: Add more escaping tests

2016-11-01  Demi Obenour <demiobenour@gmail.com>

	* src/scan.l: Fix another escaping bug in non-indented verbatim section 2 code.  I also did some reformatting.

2016-10-28  Alastair Hughes <hobbitalastair@gmail.com>

	* configure.ac: build: fix false negatives for help2man and texi2dvi HELP2MAN and TEXI2DVI (or the corresponding ac_prog variables) will
	never be zero length as they fall back to the missing script; check
	for the fall back and warn on that instead of always warning.

2016-10-28  Explorer09 <explorer09@gmail.com>

	* doc/Makefile.am: doc: Don't delete flex.1 during "make distclean".  flex.1 is pre-generated in release tarball. If we delete it, the
	next "configure and make" on the source directory will then require
	help2man unnecessarily.

2016-10-27  Alastair Hughes <hobbitalastair@gmail.com>

	* NEWS, doc/Makefile.am: Only regenerate the man page when required.  Make the flex binary an order-only prerequisite, and add back the
	prerequisites from before 7cfb440. This prevents rebuilding the man
	page whenever the flex binary is rebuilt, which causes problems if
	help2man is not installed and will never work when cross compiling.  Fixes #108.

2016-10-26  Will Estes <westes575@gmail.com>

	* NEWS, src/Makefile.am: build: no longer build PIC version of
	libfl.  The PIC version of libfl was not being built correctly. From the
	lack of bug reports around this problem, we conclude that the PIC
	version of libfl is not used and so we drop it from the build build
	targets for flex.

2016-10-25  Explorer09 <explorer09@gmail.com>

	* README.md: doc: README.md formatting fixes * Wrap everything in the raw document in 72 char per line limit.  * Proper casing for terms "Git" and "GitHub" (don't try to look
	lazy).  * Add unordered list marks when needed.  * Say `configure && make && make install` and quoted for fixed-width   font.  Signed-off-by: Kang-Che Sung <explorer09@gmail.com>

2016-10-25  Will Estes <westes575@gmail.com>

	* NEWS, configure.ac: build: version 2.6.3 begins

2016-10-24  Will Estes <westes575@gmail.com>

	* NEWS: doc: mark 2.6.2 release date

2016-10-24  Will Estes <westes575@gmail.com>

	* .gitignore, NEWS, configure.ac: build: switch xz to lzip

2016-10-20  Demi Obenour <demiobenour@gmail.com>

	* src/scan.l, tests/quotes.l: Fix M4 quotation in section 2 prologue
	and refactor duplicated code

2016-10-21  Alex Kennedy <alexzanderkennedy@gmail.com>

	* doc/flex.texi: Update flex.texi: Removed repedative wording "Flex used to" was written twice at the beginning of Chapter 9,
	paragraph 2.

2016-09-27  Demi Obenour <demiobenour@gmail.com>

	* src/dfa.c, src/gen.c, src/main.c, src/nfa.c, src/parse.y,
	src/scan.l, tests/bison_yylval_scanner.l,
	tests/include_by_push.direct.l: Improved M4 quotation This fixes M4 quotation of certain strings beginning with `yy` (in
	section 3 of the input file only) and character literals.  The new
	quotation method is also less brittle and faster.  Tests that relied on the old behavior were fixed.  Also, `yyconst` is no longer defined; use `const` (which it
	unconditionally was defined to) instead.

2016-10-19  Will Estes <westes575@gmail.com>

	* Makefile.am, configure.ac: build: for automake, flex is foreign

2016-10-19  Will Estes <westes575@gmail.com>

	* README, README.md: doc: mv README to README.md

2016-10-19  Will Estes <westes575@gmail.com>

	* README: doc: touch up README

2016-10-19  Will Estes <westes575@gmail.com>

	* README: doc: README no longer mentions sourceforge

2016-10-06  Will Estes <westes575@gmail.com>

	* NEWS: doc: update NEWS with more post-2.6.1 additions

2016-09-27  Demi Obenour <demiobenour@gmail.com>

	* src/filter.c, src/flexdef.h, src/main.c, src/misc.c,

	tests/reject.l4, tests/rescan_nr.direct.l, tests/rescan_r.direct.l,
	tests/string_nr.l, tests/string_r.l: Fix M4 quoting of section 3.  This fixes M4 quoting of section 3 of the input file, including
	escape sequences and character constants.  Tests were added to verify the behavior in section 3 with respect to
	quoting. Both escaping of quotes and quoting of potential
	macro-start characters are tested. Existing tests were also fixed to
	account for the new -- and now correct -- behavior. Many tests
	relied on the old behavior of expanding M4 macros in section 3.
	They needed to be updated for the new behavior.

2016-10-03  Mightyjo <mightyjo@gmail.com>

	* src/flex.skl, tests/.gitignore, tests/Makefile.am,
	tests/cxx_restart.ll, tests/cxx_restart.txt: Fix yyrestart(NULL)
	SEGV.

2016-09-05  Demi Obenour <demiobenour@gmail.com>

	tests/Makefile.am, tests/noansi_nr.l, tests/noansi_nr.txt,
	tests/noansi_r.l, tests/noansi_r.txt: no longer generate K&R C
	scanners

2016-09-04  Demi Obenour <demiobenour@gmail.com>

	* src/scan.l: Fix escaping of `[[` and `]]` in strings Previously, `[[` and `]]` were not escaped in strings, which led to
	bad interactions with m4.  Also, don't break strings on newline, as GCC et al support
	whitespace between a backslash and the subsequent newline.

2016-06-20  Translation Project <coordinator@translationproject.org>

	* NEWS, po/sv.po: new sv translation

2016-05-23  Demetri Obenour <demiobenour@gmail.com>

	* src/misc.c: Delete action_m4_define from misc.c This function was not used and always triggered a fatal error when
	run.

	* tests/Makefile.am: test: removed dependencies for include tests

2016-04-28  Tobias Klauser <tklauser@distanz.ch>

	* src/scanflags.c: Avoid realloc on every call of sf_push() Currently, every call to sf_push() realloc()'s _sf_stack, even if
	the maximum size _sf_max wasn't changed. As the indentation beneath
	the "if" clause already indicates, the realloc() should only be
	executed if _sf_max was increased.  Found by compiling flex with the -Wmisleading-indentation flags of
	gcc, which leads to the following warning: scanflags.c: In function �sf_push�: scanflags.c:42:5: warning:
	     this �if� clause does not guard... [-Wmisleading-indentation] if
	     (_sf_top_ix + 1 >= _sf_max) ^~ scanflags.c:44:9: note: ...this
	         statement, but the latter is misleadingly indented as if it is
	         guarded by the �if� _sf_stk = realloc(_sf_stk,
	         sizeof(scanflags_t) * _sf_max); ^~~~~~~

2016-02-27  rlar <rlar>

	* src/dfa.c, src/parse.y: dfa.c:157:24: warning: conversion to
	'size_t' from 'int' may change the sign of the result
	[-Wsign-conversion] most certainly safe cast

2016-02-27  rlar <rlar>

	* NEWS: Described more post v2.6.0 changes

2016-02-27  Will Estes <westes575@gmail.com>

	* configure.ac: build: Removed bzip2 distribiution archive

2016-02-27  Will Estes <westes575@gmail.com>

	* configure.ac: removed obsolete program check

2016-02-27  Will Estes <westes575@gmail.com>

	* configure.ac: Made some program checks more robust

2016-02-27  rlar <rlar>

	* src/flex.skl: Remove unneeded cast to int

2016-02-27  Will Estes <westes575@gmail.com>

	* src/flex.skl: Fixed incorrect integer type

2016-02-27  Will Estes <westes575@gmail.com>

	* src/flex.skl: Fix more integer types, resolves sf 184, 187

2016-02-26  Robert Larice <Robert.Larice@t-online.de>

	* src/flex.skl, src/gen.c: Removed some type conversion warnings

2016-02-26  Will Estes <westes575@gmail.com>

	* src/flex.skl: Changed another buffer size to int; resolves gh#61

2016-02-24  Will Estes <westes575@gmail.com>

	* src/flex.skl: Changed type of yy_n_chars to int; gh#53, sf#160.  The variable yy_n_chars had been of type yy_size_t which is
	incorrect given its use in read(). While it might be adviseable to
	look at defining a yy_ssize_t, there might be some issues doing this
	and so, for now, at least, we'll punt back to int.

2016-02-24  Will Estes <westes575@gmail.com>

	* src/buf.c: Fixed size of bufferallocation, resolved gh#54.  The value of n_alloc was a count, not a size. Multiplying the value
	by the element size was incorrect. That multiplication was already
	being done and having it done twice was incorrect.

2016-02-23  Tobias Klauser <tklauser@distanz.ch>

	* src/scan.l: Allow '%option noline' in flex input file, resolves
	gh#56.  Allow specifying '%option noline' in the input file, leading to the
	same effect as calling flex with the command line option --noline.  Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

2016-02-23  Tobias Klauser <tklauser@distanz.ch>

	* src/buf.c, src/main.c: Emit no #line directives if gen_line_dirs
	is false, resolves igh#55.  There are two instances in the code which will print a #line
	directive to the resulting lexer, regardless of the value of
	gen_line_dirs. Fix them, so they also respect gen_line_dirs.  Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

2016-02-16  Tobias Klauser <tklauser@distanz.ch>

	* lib/lib.c, src/gen.c, src/misc.c, src/scan.l: Converted K&R style
	function definitions to ANSI C style Consistently make use of the ANSI C function definition style
	instead of the K&R style.

2016-01-29  Tobias Klauser <tklauser@distanz.ch>

	* src/flex.skl: Used NULL constant instead of plain integer for NULL
	pointer.  The sparse static checker warns about using plain integer 0 as NULL
	pointers in the generated lexer code. Fix this by using NULL
	consistently for pointers.

2016-01-29  Tobias Klauser <tklauser@distanz.ch>

	* src/flex.skl: Marked declaration and definition of yy_fatal_error
	as noreturn.  Only the declaration of yy_fatal_error is marked with
	__attribute__((__noreturn__)) in case GCC >= 3 is used, but not the
	definition. This leads to the sparse static checker to complain
	about function declaration mismatch.  Fix it by defining a macro yynoreturn and using it for both the
	declaration and the definition of yy_fatal_error.

2016-01-27  Tobias Klauser <tklauser@distanz.ch>

	* src/flex.skl: Fixed declaration mismatch in yy_fatal_error.  The prototype declares yy_fatal_error parameter as "const char
	msg[]" while the definition uses "const char* msg" (introduced by
	commit e9d5fc713f61b) which causes the sparse static checkers to
	produce an error.  Fix this by adjusting the definition to use "const char* msg" as
	well.  Also change the C++ version accordingly so it matches the
	declaration in FlexLexer.hpp.

2016-01-23  Will Estes <westes575@gmail.com>

	* CODE_OF_CONDUCT.md: flex is for flex #NCoC

2016-01-18  Will Estes <westes575@gmail.com>

	* doc/flex.texi: Referred to github for issue tracking, no longer sf

2016-01-10  Egor Pugin <egor.pugin@gmail.com>

	* tests/reject.l4, tests/tableopts.l4: Opened files in binary mode
	explicitly

2016-01-08  OBATA Akio <obache@NetBSD.org>

	* src/Makefile.am: Linked flex binary against libintl, not libfl.   Signed-off-by: Thomas Klausner <wiz@NetBSD.org>

2016-01-08  Michael van Elst <mlelstv@NetBSD.org>

	* src/filter.c: Improved pipe-stdin hack behavior; resolves sf#198.  Signed-off-by: Thomas <Klausner wiz@NetBSD.org>

2015-12-27  Will Estes <westes575@gmail.com>

	* configure.ac, src/flexdef.h: Removed no longer needed header
	checks

2015-12-27  Will Estes <westes575@gmail.com>

	* configure.ac: Checked for reallocarray() with AC_REPLACE_FUNCS

2015-12-27  Will Estes <westes575@gmail.com>

	* src/flexdef.h, src/main.c: include libgen.h from flexdef.h, not
	main.c

2015-12-25  Michael Reed <m.reed@mykolab.com>

	* src/main.c: Replace basename2() with basename(3).  Given the following program: 	\#include <libgen.h> 	\#include <stdio.h> 	/* extracts basename from path, optionally stripping the extension
		 "\.*" * (same concept as /bin/sh `basename`, but different handling
		of extension). */ static char *basename2 (char *path) 	{ 		char   *b; 		for (b = path; *path; path++) 			if (*path == '/') 				b = path + 1; 		return b; 	} 	static void basename_compare(char *path) 	{ 		printf("basename: %s\n", basename(path)); 		printf("basename2: %s\n\n", basename2(path)); 	} 	int main (int argc, char *argv[]) 	{ 		// From http://pubs.opengroup.org/onlinepubs/9699919799/ 		// ``Sample Input and Output Strings'' 		basename_compare("/usr/lib"); 		basename_compare("/usr/"); 		basename_compare("/"); 		basename_compare("///"); 		basename_compare("//usr//lib//"); 		return 0; 	} ... and the program's output: 	basename: lib 	basename2: lib 	basename: usr 	basename2: 	basename: / 	basename2: 	basename: / 	basename2: 	basename: lib 	basename2: ... we can see that basename2() behaves the same as basename(3) in
	the average use case, but messes up pretty severely in others.
	Besides that, basename(3) is mandated by POSIX so should be present
	on modern Unix-like systems, so we shouldn't define it ourselves.  Some notes: - it doesn't appear to be mentioned in POSIX, but OpenBSD's
	  basename(3) returns NULL if the returned path componenet is >
	  PATH_MAX, so add a check for that - basename(3) shouldn't return an empty string, so remove the   program_name[0] != '\0' check

2015-12-25  Michael Reed <m.reed@mykolab.com>

	* src/main.c: Simplify basename2().  It's only call site does not activate the `strip_ext` code path, so
	the function can be simplified a lot.  While here, remove a double
	assignment.

2015-12-25  Michael Reed <m.reed@mykolab.com>

	* src/flex.skl, src/misc.c: Cleaned up __STDC__ #ifdefs.  Assuming a compiler conforming to the ISO C standard is used, i.e.,
	__STDC__ is defined to 1, YY_USE_CONST is always defined and can be
	eliminated.

2015-12-25  Michael Reed <m.reed@mykolab.com>

	* src/flexdef.h, src/main.c, src/scanopt.c, src/scanopt.h,
	src/sym.c: Remove remaining use of PROTO

2015-12-21  Serguey Parkhomovsky <xindigo@gmail.com>

	* src/buf.c: buf.c: use snprintf

2015-12-19  Will Estes <westes575@gmail.com>

	* configure.ac: build: reformatted AC_CHECK_FUNCS for readability

2015-12-17  Will Estes <westes575@gmail.com>

	* src/scanopt.c: correct function prototype

2015-12-15  Michael Reed <m.reed@mykolab.com>

	* src/main.c, src/scanopt.c, src/sym.c, src/tblcmp.c: Remove more
	instances of PROTO

2015-12-15  Michael Reed <m.reed@mykolab.com>

	* src/main.c: Removed prototype for main().  It's not called anywhere else so the prototype is not needed.  See
	the C99 standard [1], section 5.1.2.2.1 for more info.  [1]: http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1256.pdf

2015-12-13  Michael McConville <mmcco@mykolab.com>

	* src/dfa.c, src/gen.c, src/nfa.c, to.do/unicode/main.c,
	to.do/unicode/tblcmp.c: Removed more instances of PROTO, ansifying.

2015-12-13  Will Estes <westes575@gmail.com>

	* README: Noted github for issue tracking and pull requests

2015-12-13  Michael McConville <mmcco@mykolab.com>

	* README: Reformatted README; removed sf bug tracking link.

2015-12-13  Michael McConville <mmcco@mykolab.com>

	* src/gen.c, to.do/unicode/gen.c: Removed macros for indentation
	level.  Just increment or decrement the indentation counter. That's less to
	remember and makes the code more readable.  w# Please enter the commit message for your changes. Lines starting

2015-12-12  Mike Frysinger <vapier@gentoo.org>

	* tests/Makefile.am, tests/testwrapper.sh: tests: fixed paths to
	input files.  The current test wrapper works only when the inputs are specified
	using relative paths.  If they're specified with absolute paths, the
	driver fails to detect the inputs because it always prepends the
	input dir name which itself is a relative path: $ cd tests $
	./testwrapper.sh -d . -i $PWD/reject.txt -t ./reject_ver.table
	<fails to open inputs> This normally doesn't show up because people run `./configure` or,
	for out of tree builds, `../configure`.  But if you happen to run
	configure with an absolute path, then automake tends to generate
	absolute paths as well leading to test failures.  Fix all of this by dropping the implicit input directory prepending.  - INPUT_NAME is often a list of files, not just a single one - the input directory is used to find the testname tables which are   usually generated, so it's impossible to use files from both
	  source and build directories - most of the time, the full/correct path is already specified

2015-12-12  Mike Frysinger <vapier@gentoo.org>

	* configure.ac: configure: fixed realloc test.  The [] characters are used for quoting in m4, so the attempt to use
	them in place of `test` fails yielding the warning at build time: .../flex/configure: line 20222: no: command not found

2015-12-12  Michael McConville <mmcco@mykolab.com>

	* src/flexdef.h: Started removal of PROTO macro.  The PROTO macro is no longer needed. Additionally, its usage is
	inconsistent, so we began removing it.

2015-12-12  Michael Reed <m.reed@mykolab.com>

	* Makefile.am, src/main.c: Removed SHORT_FILE_NAMES preprocessor
	symbol.  As a relic of MS-DOS, we don't need this.  It's never defined; see 13b5b214f53d1c3354a7ab910bd160c126df1331.  Removed additional MSDOS ifdef.

2015-12-11  Michael McConville <mmcco@mykolab.com>

	* configure.ac, lib/reallocarray.c, src/flexdef.h: Added new
	function reallocarray.  This is taken from OpenSSH Portable, which in turn takes it from
	OpenBSD.  reallocarray wraps the stdlib's realloc function. It takes two size
	arguments and checks for overflow, like calloc, but doesn't zero the
	memory. Therefore, it allows us to do overflow-safe array
	reallocations and overflow-safe unzeroed array allocations, which
	the stdlib allocation functions don't.  We have a bunch of specific array allocation macros, none of which
	check for overflow. reallocarray should be able to replace them.

2015-12-11  Michael McConville <mmcco@mykolab.com>

	* src/flexdef.h: Removed MS-DOS, VMS macros.  Given the age of the MS-DOS and VMS platforms, it's likely that no
	one is building flex on them any more. Additionally, the preferred
	approach is to test for particular platform features rather than to
	test for particular platforms.

2015-12-12  Will Estes <westes575@gmail.com>

	* src/flexdef.h, src/main.c: Made search for m4 more explicit.

2015-12-12  Will Estes <westes575@gmail.com>

	* src/flex.skl: Returned 0 from yywrap() instead of EOF

2015-12-11  Will Estes <westes575@gmail.com>

	* src/libmain.c: Changed end of main() in libmain to exit(0)

2015-12-11  Will Estes <westes575@gmail.com>

	* NEWS, configure.ac: Mentioned v2.6.1; documented some changes
	since v2.6.0

2015-12-11  Will Estes <westes575@gmail.com>

	* README: Updated build documentation; finished sf#155.  Removed version numbers for build tools. Noted that version
	requirements for build tools will be noted in configure.ac. Expanded
	documentation of building texinfo based docs.

2015-12-11  Will Estes <westes575@gmail.com>

	* doc/Makefile.am: Removed flex.pdf from distribution; partially
	fixed sf#155

2015-12-11  Will Estes <westes575@gmail.com>

	* src/flex.skl: Commented in C style in skeleton; fixed sf#195

2015-12-10  Will Estes <westes575@gmail.com>

	* .gitignore: Ignored autoscan files

2015-12-09  Will Estes <westes575@gmail.com>

	* configure.ac: Checked for ranlib and strdup() at configure time

2015-12-09  Michael McConville <mmcconville@mykolab.com>

	* src/flexdef.h, src/misc.c, src/tblcmp.c, to.do/unicode/flexdef.h,
	to.do/unicode/misc.c, to.do/unicode/tblcmp.c: Replace zero_out()
	with stdlib's memset.

2015-12-09  Michael McConville <mmcconville@mykolab.com>

	* src/flex.skl: Removed memory allocation casts.

2015-12-09  Michael McConville <mmcconville@mykolab.com>

	* src/flexdef.h: Removed alloca() configuration.  Since alloca() is dangerous, depricated, we remove it.

2015-12-09  Michael McConville <mmcconville@mykolab.com>

	* src/flexdef.h: Removed implementation of isascii().  POSIX defines isascii(), so it's likely present on anything
	weactually build flex on these days.

2015-12-09  Michael McConville <mmcconville@mykolab.com>

	* src/main.c, src/scanopt.c, src/tables.c: Removed NULL-checks
	before free()

2015-12-08  Michael McConville <mmcconville@mykolab.com>

	* src/buf.c, src/dfa.c, src/flexdef.h, src/gen.c, src/scan.l,
	to.do/unicode/flexdef.h, to.do/unicode/scan.l: Removed flex_free()i,
	corrected buf_destroy logic.  As with flex_alloc(), replace with direct calls to free().  The function buf_destroy is now null safe and the logic was
	corrected to free() correctly.

2015-12-08  Michael McConville <mmcconville@mykolab.com>

	* src/filter.c, src/flexdef.h, src/misc.c, src/scan.l,
	src/scanflags.c, to.do/unicode/flexdef.h, to.do/unicode/misc.c,
	to.do/unicode/scan.l: Removed flex_realloc().  As with flex_alloc(), replace calls to flex_realloc(), which was
	just a wrapper around realloc().

2015-12-08  Michael McConville <mmcconville@mykolab.com>

	* src/buf.c, src/filter.c, src/flexdef.h, src/main.c, src/misc.c,
	src/regex.c, src/scan.l, src/scanflags.c, src/sym.c,
	to.do/unicode/flexdef.h, to.do/unicode/misc.c, to.do/unicode/scan.l:
	Removed flex_alloc; cleaned up style.  The function flex_alloc() was just a wrapper around malloc(). Since
	this only added unclarity, and the flex_alloc() function is likely a
	legacy of olden times, remove it in favor of calls to malloc()
	directly.  Style elements cleaned up:  * superfluous spacing around parentheses  * non-constant initialization in variable declarations  * needless casts  * almost all uses of assignments as subexpressions

2015-12-07  Michael McConville <mmcconville@mykolab.com>

	* src/dfa.c, src/flexdef.h, src/gen.c, src/main.c, src/scan.l,
	src/scanopt.c, tests/bison_nr_scanner.l,
	tests/bison_yylloc_scanner.l, tests/bison_yylval_scanner.l,
	tests/mem_nr.l, tests/mem_r.l, tests/pthread.l, tests/string_nr.l,
	tests/string_r.l, tests/yyextra.l, to.do/unicode/scan.l: Remove
	allocation casts

2015-12-07  Will Estes <westes575@gmail.com>

	* src/.gitignore, src/Makefile.am: Built flex with itself.  Changes in scan.l need to be built into flex with the same version
	of flex in some cases. Since this build requirement is minimal, we
	simply bootstrap flex unconditionally.  We intentionally exclude from version control the bootstrap
	artifacts as the extra copy of the lexer, the intermediate scanner
	and the bootstrap executable are not of interest.

2015-12-05  Michael McConville <mmcconville@mykolab.com>

	* src/buf.c, src/dfa.c, src/main.c, src/nfa.c, src/parse.y,
	src/scan.l, src/scanopt.c, src/sym.c, to.do/unicode/main.c,
	to.do/unicode/scan.l: Use NULL rather than (type *) 0.

2015-12-05  Michael McConville <mmcconville@mykolab.com>

	* src/flexdef.h, src/misc.c, src/sym.c, to.do/unicode/flexdef.h,
	to.do/unicode/misc.c: Replace copy_unsigned_string() with xstrdup().  Like copy_string(), copy_unsigned_string() is just a clone of the
	stlib's strdup(). We only use it twice. I'm pretty confident that
	char signedness is irrelevant in this case.

2015-12-04  Akim Demaille <akim@lrde.epita.fr>

	* src/FlexLexer.h: Cleaned up white space.

2015-12-04  Akim Demaille <akim@lrde.epita.fr>

	* src/FlexLexer.h: Removed struct keyword before yy_buffer_state

2015-12-04  Akim Demaille <akim@lrde.epita.fr>

	* examples/testxxLexer.l, src/FlexLexer.h, src/flex.skl, src/main.c:
	Replaced FLEX_STD macro with std::.  The std:: construct exists as of C++98, so we can simply assume it
	is supported.

2015-12-04  Akim Demaille <akim@lrde.epita.fr>

	* src/Makefile.am: Generated skel.c explicitly in srcdir.  Rewrote the target for skel.c to explicitly mention the srcdir. This
	should help when building flex from a directory outside the flex
	tree. Spread the rule out over several lines to enhance readability.

2015-12-04  Akim Demaille <akim@lrde.epita.fr>

	* autogen.sh: Called glibtoolize if libtoolize run fails.  On Mac OS X, libtoolize is known as glibtoolize. In cases where
	libtoolize is not present, then calling glibtoolize when
	bootstrapping the build system gives more folks a shot at getting
	flex built from the ground up.

	* configure.ac: Checked for (g)texi2dvi. Better bison, help2man
	checks.  Added test for presence of (g)texi2dvi program. Gave notice if
	texi2dvi is unavailable and set TEXI2DVI=: to avoid giving users
	headaches.  Enhanced tests for bison and help2man with notices when the programs
	aren't found.  Set their program variables to use the missing script
	in build-aux since it's compatible with them.

	* src/flexdef.h, src/misc.c, src/parse.y, src/scan.l, src/sym.c,
	src/tables.c, to.do/unicode/flexdef.h, to.do/unicode/misc.c,
	to.do/unicode/scan.l: Made string copying more standard.  copy_string() was a clone of the stdlib's strdup(). For safety,
	simplicity, and speed, we should use that instead. We introduce
	xstrdup() which wraps strdup() in a failure upon memory allocation
	errors.

	* src/scan.l: Error on unbalanced parentheses in rules section.

	* src/Makefile.am: Cleaned up BUILT_SOURCES list.  Removed reference to skel.c as a built source since other make rules
	cover this case.

	* src/Makefile.am: Sorted file names in flex_SOURCES

	* src/ecs.c, src/flexdef.h, src/main.c, src/misc.c, src/scan.l,
	src/scanopt.c, src/sym.c, src/tblcmp.c: Replaced CHAR macro with
	unsigned char type.  Thanks to Michael McConville for pointing out that the old Char
	macro causes problems with static analysis.  The macro has been
	removed and replaced with 'unsigned char' throughout the flex
	sources. The macro is not needed at best and was confusing at worst.
	It was not used in any of the example files nor was it mentioned in
	the manual at all.

	* configure.ac: updated syntax of AC_INIT call as per autoupdate

2015-11-21  Will Estes <westes575@gmail.com>

	* tests/Makefile.am: removed extra call to a _CPPFLAGS variable

2015-05-14  Stefan Reinauer <stefan.reinauer@coreboot.org>

	* src/buf.c, src/ccl.c, src/dfa.c, src/ecs.c, src/gen.c,
	src/main.c, src/misc.c, src/nfa.c, src/parse.y, src/scan.l,
	src/scanopt.c, src/sym.c, src/tblcmp.c: Switch function definitions
	from mixed K&R to consistent ANSI C.  flex was using K&R function definitions for some functions and ANSI
	C style in others, sometimes even in the same file. Change the code
	to consistently use ANSI C.  Signed-off-by: Stefan Reinauer <stefan.reinauer@coreboot.org>

	* tests/Makefile.am: Used in-tree header file for c++ tests.
