	* src/tgbatest/scc.test: Redirect stdout into file `stdout'

	Number states using negative values and SCCs using nonnegative
	values.

	Before this change states were numbered using positive values and
	SCCs using negative values.  That meant the user had to work with
	negative values.  With this changes, the nonnegative values used
	to label SCCs can also directly be used as index in the scc_map_.

	* src/tgbaalgos/scc.hh (scc_map::scc_of_state,
	scc_map::cond_set_of, scc_map::acc_set_of, scc_map::states_of,
	scc_map::initial, scc_map::scc_type, scc_map::succ,
	scc_map::accepting): Adjust prototypes to take or return unsigned
	arguments.
	* src/tgbaalgos/scc.cc: Adjust prototypes of the above functions.
	(scc_map::build_map, scc_map::relabel_component): Number states
	using negative values, and SCCs using nonnegative values.
	(dump_scc_dot): Adjust to use nonnegative values.

	Store the scc_map_ as a vector instead of a std::map.  There is no
	point in using a map since the SCC are numbered in sequence.

	* src/tgbaalgos/scc.hh (scc_map::relabel_component): Return the
	number of the SCC instead of taking it as argument.
	(scc_map::scc_num_): Delete this variable.  scc_map_.size() gives
	the same information.
	(scc_map::scc_map_type): Define using std::vector instead of
	std::map.
	* src/tgbaalgos/scc.cc: Adjust all uses.

	scc_map::cond_set_of, scc_map::acc_set_of, scc_map::states_of):
	New functions.
	(scc_map::scc::conds): New attribute.
	(dump_scc_dot): Take an optional VERBOSE argument.
	* src/tgbaalgos/scc.cc (scc_map::scc_of_state,
	scc_map::cond_set_of, scc_map::acc_set_of, scc_map::states_of):
	Implement these new functions.
	(dump_scc_dot): Display number of states, conditions and
	acceptance conditions, with VERBOSE is set.
	(build_map): Fill the new scc_map::scc::cond field.

	* src/tgbaalgos/scc.cc (scc_map::relabel_component): Make sure
	that the old label of each state is strictly positive.  The
	previous assertion (inherited from gtec) of "!= -1" is wrong,
	because all negative values are now used to number SCCs.

	automaton operators such as Strong=G(F($0))->G(F($1)) and
	G=R(false, $0).

	notation for binary automaton operators.

	Add support for ELTL (AST & parser), and an adaptation of LaCIM
	for ELTL.

        * configure.ac: Adjust for src/eltlparse/ and src/eltltest/
	directories, and call AX_BOOST_BASE.
	* m4/boost.m4: New file defining AX_BOOST_BASE([MINIMUM-VERSION]).
	* src/Makefile.am: Add eltlparse and eltltest.
	* src/eltlparse/: New directory.  Contains the ELTL parser.
	* src/eltltest/: New directory.  Contains tests related to
	ELTL (parser and AST).
	* src/ltlast/Makefile.am: Adjust for ELTL AST files.
	* src/ltlast/automatop.cc, src/ltlast/automatop.hh: New files.
	Represent automaton operators nodes used in ELTL ASTs.
	* src/ltlast/nfa.cc, src/ltlast/nfa.hh: New files.  Represent
	simple NFAs used internally by automatop nodes.
	* src/ltlast/allnode.hh, src/ltlast/predecl.hh,
	src/ltlast/visitor.hh: Adjust for automatop.
	* src/ltlvisit/basicreduce.cc, src/ltlvisit/clone.cc,
	src/ltlvisit/clone.hh, src/ltlvisit/contain.cc,
	src/ltlvisit/dotty.cc, src/ltlvisit/nenoform.cc,
	src/ltlvisit/postfix.cc, src/ltlvisit/postfix.hh,
	src/ltlvisit/reduce.cc, src/ltlvisit/syntimpl.cc,
	src/ltlvisit/tostring.cc: Because LTL and ELTL formulae share the
	same class hierarchy, LTL visitors need to handle automatop nodes
	to compile.  When it's meaningful the visitor applies on automatop
	nodes or simply assert(0) otherwise.
	* src/tgba/tgbabddconcretefactory.cc (create_anonymous_state),
	src/tgba/tgbabddconcretefactory.hh (create_anonymous_state): New
	function used by the LaCIM translation algorithm for ELTL.
	* src/tgbaalgos/Makefile.am: Adjust for eltl2tgba_lacim* files.
	* src/tgbaalgos/eltl2tgba_lacim.cc,
	src/tgbaalgos/eltl2tgba_lacim.hh: New files.  Implementation of
	the LaCIM translation algorithm for ELTL.
	* src/tgbaalgos/ltl2tgba_fm.cc, src/tgbaalgos/ltl2tgba_lacim.cc:
	Handle automatop nodes in the translation by an assert(0).
	* src/tgbatest/Makefile.am: Adjust for eltl2tgba.* files.
	* src/src/tgbatest/eltl2tgba.cc, src/tgbatest/eltl2tgba.test: New

	Update parsers to work with Bison 2.4.1.

	* HACKING: Mention that we require Bison >= 2.4 for developers.
	* src/evtgbaparse/evtgbaparse.yy, src/tgbaparse/tgbaparse.yy,
	src/ltlparse/ltlparse.yy: The sections "%{ ... %}" should now be
	renamed "%code requires { ... }" or "%code { ... }" depending on
	whether they should end up in the parser's header file or its cc
	file.  Also use %language, %locations, %defines, instead of
	command-line arguments.
	* src/evtgbaparse/Makefile.am, src/tgbaparse/Makefile.am,
	src/ltlparse/Makefile.am: Remove the --locations, --defines
	and --languages in the call to bison.  Add -Wall -Werror to
	catch more errors.
	Thanks to Akim Demaille <akim@lrde.epita.fr> for the help.

	Reorganize this function so that syntactically there is only one
	loop over the successors, and not two.  Call reintroduce the call
	to couvreur99_check_shy::state_index(), needed by SSP, and
	suppress that to index_and_insert introduced on 2004-12-29.  Also
	split the "group" option in two: "group" and "group2".  "group2"
	is the equivalent of the older "group", while the new "group" is
	weaker and faster.
