degeneralization.  Also error out when -R3b is used on non
symbolic automata.

Let "make dvi" work on Ubuntu.

* doc/lbtt.texi (The formula generation algorithm): Use op^\prime
instead of op', because etex on Ubuntu hangs (an infinite loop?)
on the later when texi2dvi tries to compile a dvi.

Get rid of some "deprecated conversion from string constant to
`char*'" warnings.

* examples/bddcalc/parser_.h (yyerror): Declare the format
as a "const char*".
* examples/bddcalc/parser.yxx (yyerror): Likewise.

* src/ltlvisit/length.cc (visit(multop*)): New function. "a & b &
c" has length 5, not 4, even though it is stored as And(a,b,c).
This caused reduc.test to fail on some formulae.

* src/tgbaalgos/randomgraph.cc: Fix the copyright and make it fit
on 80 columns.

Kill some warnings on Ubuntu.

* src/bddio.c (bdd_load): Check the return value of fscanf() to
kill a warning.

* src/tgba/taatgba.cc (taa_tgba_formula::~taa_tgba_formula):
Really destroy all formulae, not only half of them.

* src/ltltest/reduc.cc: Add an option -f to read a lost of
formulae from a file.  Running a process for each formula was
too slow.  Also add an option -h to hide reduced formulae.
* src/ltltest/reduc.test: Simplify accordingly.

* src/tgbatest/emptchk.test: Move the newly added test ...
* src/tgbatest/emptchke.test: ... here, with other explicit test.
Also test more algorithms.

* src/tgbaalgos/gtec/ce.cc (couvreur99_check_result::acss_states):
Delete the iterator after using it.
* src/tgbatest/emptchkr.test: Run 'randtgba -z' with valgrind too.

* src/tgbaalgos/gv04.cc (push): Fix the tracking of the accepting
link.  This bug was discovered on a random generated graph with
a complex accepting cycle.
* src/tgbatest/emptchk.test: Add the troublesome graph as
test case.

* src/ltlast/automatop.cc, src/ltlast/automatop.hh: Rename nfa as

the patch from 2007-02-06 which silently replaced the use of state
index by state pointers.  Storing states pointer in this map cause
some non-determinism because of the memory layout.  It was almost
impossible to reproduce bugs found by tests based on randtgba.
