	* 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

	* defs.h: split-out xdecls[]

	* VERSION: bump

	* configure: regen

	* aclocal.m4: add CF_REMOVE_DEFINE, needed by CF_ADD_CFLAGS

	* aclocal.m4:
	resync with my-autoconf CF_ADD_CFLAGS and CF_DISABLE_ECHO changes.

2008-11-26  Thomas Dickey  <tom@crayon>

	* verbose.c, main.c, defs.h, mkpar.c, reader.c:

	fixes for gcc -Wwrite-strings

	* test/calc.tab.c, test/error.tab.c, test/ftp.tab.c, test/grammar.tab.c:
	generate the tables as static-const (this is an interface change)

	* output.c: realign columns in start_table()

	* output.c:

2008-08-25  Thomas Dickey  <tom@crayon>

	* test/ftp.tab.c: regen'd

	* reader.c:
	improve the left-curly fix by testing after blanks, to avoid having a
	" {" at the beginning of a line.

	* test/error.tab.c, test/grammar.tab.c: regen'd

	* output.c:
	move the remaining newline-counting into write_XXX functions.

	simplify part of the output_file formatting using new functions, e.g.,
	start_int_table(), output_newline().

	* 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
	it simpler to edit (not confuse editors which look for a left-curly in the
	first column as if it were the beginning of a function).

	* skeleton.c: minor fixes to avoid gcc -Wconversion warnings

	* output.c: align the #define's produced for "-p" option

	* test/run_test.sh: use the "-p" option for better coverage.

	add hook for auditing memory leaks

	* defs.h: add hooks for auditing memory leaks

	* configure: regen'd

	* configure.in:
	use CF_DISABLE_LEAKS, which combines --disable-leaks, --with-valgrind,
	--with-dbmalloc and --with-dmalloc

	* aclocal.m4: add CF_DISABLE_LEAKS and CF_WITH_VALGRIND

2005-08-13  Matt.Kraai

	* output.c:

	* main.c:
	exit after printing version.  Otherwise "yacc -V" will exit with an erro
	after printing the usage message.

	* test/calc.tab.c, test/error.tab.c, test/ftp.tab.c, test/grammar.tab.c:
	regenerated after skeleton-changes

	* skeleton.c: replace a few -1's with YYEMPTY

	* skeleton.c: adapt yygrowstack() and related definitions from FreeBSD

	* test/run_test.sh:
	filter out lines with YYPATCH, since that will change with each update

	* yacc.1: add -V option

	* main.c: add -V option to print the version.
	simplify option-parsing by moving the duplicate logic for setting flags into
	new function setflag().

	add macros to define VERSION in terms of the (numeric) YYMAJOR, YYMINOR and
	YYPATCH symbols.

	* lalr.c, lr0.c, mkpar.c, defs.h, closure.c, warshall.c, output.c, verbose.c, graph.c, reader.c, main.c, symtab.c:
	reduce externs by making static the procedures that are not referenced outside
	the module in which they are defined.

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

	* VERSION: RCS_BASE

	* main.c:
	add "-o" to usage message.  It is too long for a single line; rewrite usage()
	to show one option per line.

2005-05-03  Thomas Dickey  <tom@crayon>

	* main.c: add -o option, to work with scripts that assume bison.
	simplify create_file_names() with a macro.
	simplify done() with a macro.
	adapt fix from FreeBSD for signal race, e.g., if done() is interrupted by
	onintr(), do not flush output via exit(), but use _exit() instead.

	* defs.h: remove unnecessary externs for main.c

	* yacc.1: add -o option

	* graph.c: remove unused parameter

	Sylvain Schmitz <schmitz@i3s.unice.fr>:
	add graphical output of the LALR(1) automaton for graphviz,
	associated with command-line option `-g'

	add AC_ARG_PROGRAM to make --program-prefix, etc., work.

	* defs.h: remove action_file_name, etc., since we use tmpfile() now.

	* main.c:
	use tmpfile() for opening the working files.  This quiets a warning
	advising the use of mkstemp().

	* output.c:
	Do not close temporary-files here, since they are opened with tmpfile().
	Just rewind them, and they're ready to read back the data stored in them.

	* test/grammar.output, test/grammar.tab.c, test/grammar.tab.h: RCS_BASE

	* makefile.in: turn on "make check" rule

	* test/calc.output, test/run_test.sh, test/calc.tab.h: RCS_BASE
