2013-03-04  Thomas E. Dickey  <tom@invisible-island.net>

	* package/debian/changelog, VERSION, package/byacc.spec: bump

	* aclocal.m4:
	adapt tweak from Dave Becket to work around long-ago breakage in "new" autoconf.

	* output.c:
	fix bogus #include if "-i" is given but not "-d" (report by Richard Mitton).
	also while testing that, found a case where the union_file is unused; added
	a check for address that.

	* test/ftp.output, test/ftp.tab.c, test/ftp.tab.h: regen

	* test/ftp.y: fix most compiler warnings for "make check_make"

	* test/calc1.tab.c: regen

	* test/calc1.y: fix most compiler warnings for "make check_make"

	* test/calc.tab.c, test/calc1.tab.c, test/calc2.tab.c, test/calc3.tab.c, test/code_calc.code.c, test/code_error.code.c, test/error.tab.c, test/ftp.tab.c, test/grammar.tab.c, test/pure_calc.tab.c, test/pure_error.tab.c, test/quote_calc-s.tab.c, test/quote_calc.tab.c, test/quote_calc2-s.tab.c, test/quote_calc2.tab.c, test/quote_calc3-s.tab.c, test/quote_calc3.tab.c, test/quote_calc4-s.tab.c, test/quote_calc4.tab.c:
	regen

	* skeleton.c: quiet a gcc conversion-warning in yygrowstack()

	* configure: regen

	* aclocal.m4:
	another fix for CF_GCC_VERSION to handle Debian's modification of gcc message.

2013-02-10  Thomas E. Dickey  <tom@invisible-island.net>

	* config.sub, config.guess: 2013-02-04

2012-10-03  Thomas E. Dickey  <tom@invisible-island.net>

	* package/debian/changelog, package/byacc.spec, VERSION: bump

	* configure: regen

	* configure.in: moved AC_PROG_CC_STDC call into CF_PROG_CC

	* aclocal.m4:
	moved AC_PROG_CC_STDC call into CF_PROG_CC and (for other uses than byacc)
	the CF_PROG_CC macro provides the CF_ANSI_CC_REQD for the 2.13 flavor.

	* aclocal.m4, configure.in:
	Arian's change dropped my check for misused $CC variable - restore that with
	alternate macro CF_PROG_CC.

2012-10-03  Adrian.Bunk

	* aclocal.m4:
	suggested patch: drop CF_ANSI_CC_REQD, CF_ANSI_CC_CHECK, CF_PROG_EXT since
	they are not needed.

2012-10-03  Thomas E. Dickey  <tom@invisible-island.net>

	* aclocal.m4:
	split-out CF_CC_ENV_FLAGS from CF_ANSI_CC_CHECK to avoid losing it in
	Adrian's suggested changes.

	* aclocal.m4:
	CF_CLANG_COMPILER - check if the given compiler is really clang.

	* aclocal.m4:
	add check for clang to CF_GCC_WARNINGS.  modify CF_GCC_WARNINGS to work around
	old gcc warning:  ncurses change to (try to) use gnatgcc exposed gnatgcc 2.8.1
	on my Sarge system (versus 3.3.5 for the normal gcc).  The 2.8.1's
	pointer-arithmetic checks fell afoul of gcc's misuse of void* in string.h; work
	around by excluding that check for pre-3.x compilers.

	* aclocal.m4:
	modify CF_GCC_ATTRIBUTES so that autoheader is able to see the definitions
	provided by this macro.  use AC_DEFINE_UNQUOTED() in CF_GCC_ATTRIBUTES rather
	than appending to confdefs.h, since long-ago concern about the ability to
	pass-through parameterized macros appears to be not a problem, testing with
	2.13 and 2.52

2012-10-03  Adrian.Bunk

	* aclocal.m4:
	add parameter to AC_DEFINE_UNQUOTED() to allow it to be recognized by
	autoheader, updated macros:
		CF_CHECK_CACHE
		CF_DISABLE_LEAKS
		CF_MKSTEMP
		CF_MIXEDCASE_FILENAMES
		CF_NO_LEAKS_OPTION

2012-10-03  Thomas E. Dickey  <tom@invisible-island.net>

	* aclocal.m4:
	move existence-check for mkstemp out of the AC_TRY_RUN, to help with
	cross-compiles

2012-10-02  Thomas E. Dickey  <tom@invisible-island.net>

	* config_h.in:
	Adrian Bunk request - replace this with the output from autoheader

2012-09-29  Adrian.Bunk

	* configure.in:
	suggested change: replace CF_ANSI_CC_REQD by AC_PROG_CC_STDC (since no
	check is needed anymore for standard C compilers), drop AC_CONST (same
	reason), modify AC_OUTPUT to rely upon template generated by autoheader.
	bump requirement to autoconf 2.52.20011201 and drop check for CF_PROG_EXT
	as being obsolete with autoconf 2.52x

	* configure.in, main.c: drop check for atexit, because it is standard C

	* makefile.in: add assignment for datarootdir variable.

2012-05-26  Thomas E. Dickey  <tom@invisible-island.net>

	* package/debian/changelog, package/byacc.spec, VERSION: bump

	* reader.c:
	some versions of gcc may warn that bp is not set in mark_symbol, e.g.,
	if GCC_NORETURN is not handled; appease the compiler.

	* reader.c:
	use the declared types Assoc_t and Value_t in some places where compiler only
	cared about char versus short.

	* reader.c:
	use TMALLOC() and TREALLOC() macros to simplify allocation/reallocation
	(no object change)

	* defs.h:
	add fallbacks for GCC_NORETURN and GCC_UNUSED to make it simpler for *BSD
	packagers to build without configure script.  Also remove duplicate declaration
	of pure_parser variable (prompted by patch by Baptiste Daroussin).

	Also define new TMALLOC and TREALLOC macros to simplify/replace MALLOC and
	REALLOC macros.

	* symtab.c:
	use TMALLOC() and TREALLOC() macros to simplify allocation/reallocation
	(no object change)

2012-05-25  Thomas E. Dickey  <tom@invisible-island.net>

	* output.c, main.c, verbose.c, mkpar.c, lr0.c:
	use TMALLOC() and TREALLOC() macros to simplify allocation/reallocation
	(no object change)

	* yacc.1, output.c, main.c, defs.h:
	add "-s" option to suppress generating #define's based on string contents
	in a %token statement.  For instance
		%token EQLS "Equals"
	would generate
		#define EQLS 256
		#define Equals 257
	Simply suppressing the second #define makes the behavior closer to yacc.
	(report by Paulo Andrade).

	regen - changes for "-i" option move the global/impure variables near the
	macros that may add a prefix, etc.

	* skeleton.c, output.c, defs.h: changes to support "-i" option.

2011-09-06  Thomas E. Dickey  <tom@invisible-island.net>

	changes to support running "make check" in a separate build-tree

	* main.c: add "-P" to usage message

	* reader.c: use UCH() macro to hide casts.

2010-06-07  Andres.Mejia

	* main.c, output.c, reader.c, defs.h, skeleton.c:
	Fix the output order of the generated parse code file.  This allows for
	the use of YYPARSE_PARAM, by having the output that checks for
	YYPARSE_PARAM to be defined come after the C code block in the
	definitions section of a yacc file.

	Implement support for YYLEX_PARAM, similar to bison.  This is useful for
	support for building reentrant lexers with flex.

	Fix a compatibility issue with bison's pure-parser option.  Bison
	defines yylex as sending at least one parameter, &yylval, as the first
	parameter and doesn't seem to have an easy way to remove that parameter.
	This on the other hand is rather convenient to support saving to yylval
	from flex when building reentrant lexers and parsers.

	Add support for the %parse-param and %lex-param directives used in
	bison.  This change bears some similarity to NetBSD's changes to byacc
	at http://www.mail-archive.com/source-changes-full@netbsd.org/msg08143.html

	Bison allows for POSIX yacc emulation via a yacc directive in the yacc
	file, and also via a command line switch.  Implement this feature as a
	no-op for byacc, since byacc is designed to be POSIX yacc compatible
	anyway.  This allows for better compatibility with yacc sources written
	for bison.

2010-06-07  Thomas E. Dickey  <tom@invisible-island.net>

	* VERSION: bump to 2010/06/07

2010-06-06  Thomas E. Dickey  <tom@invisible-island.net>

	* test/calc.tab.c, configure: regen

	* skeleton.c:
	move #include's down into the generated code, to allow user-defined code
	to override feature definitions, particularly with stdlib.h (request by
	Marcus Kool).

	* lr0.c, error.c, reader.c, defs.h:
	strict gcc 3.4.6 warnings on 64-bit platform

	* package/debian/copyright: add copyright notices for non-PD files

	* package/debian/changelog:
	incorporated scripts in upstream to use for test-builds

	* makefile.in: drop mkdirs.sh, just use "mkdir -p"

	* yacc.1: document -P and bison-extensions

	* test/ftp.tab.c, test/grammar.tab.c, test/calc.tab.c, test/error.tab.c:
	regen

	* output.c: implement %pure-parser

	* skeleton.c:
	implement %pure-parser, like bison.  To help with this, changed the stack
	variables, putting them into a struct.

	* reader.c: implement %pure-parser

	* defs.h: modified skeleton to support %pure-parser feature

	* main.c: add -P option to set %pure-parser

	* output.c:
	make -r and -p options work together.  The -r option splits the generated
	parser into code/table files; for this case we cannot use static data.
	Also, we have to repeat the #define's used for prefix (-p) as well as the
	redeclaration of yyparse().  Finally, allow any of the prefixed names to
	be overridden, e.g., by passing a -D option to the compiler.  Make that
	a little more readable by putting a blank line before each chunk.

	* defs.h: add definitions for %pure-parser

	* skeleton.c:
	put blank line before/after the redeclaration of yyparse()

	* output.c: allow for other program redefining yylex()

	* skeleton.c:
	split-off xdecls[] array, to move declaration of yyparse() after #define's

	* reader.c:
	modify copy_action() to indent the first character, it if is is left-curly
	brace.  That makes the output look more like the original, as well as makes

	the VERSION file holds the patch-date.  Define YYPATCH, so this will be
	compiled into the skeleton.

	* VERSION: patch-level for byacc

	* main.c:
