Because only the configure macros of spot::srand() had been updated to
the introduction of _config.h, rand() was used even if drand48() was
available, and yet srand48() was being called by spot::srand(). The
consequence is that setting the seed with srand48() had not effect on
the value returned by rand(). Reported by Etienne Renault.
* src/misc/random.cc (drand): Fix configure macros used.
* src/misc/acccompl.hh, src/misc/acccompl.cc (AccCompl): Rename to
acc_compl.
* src/tgbaalgos/simulation.cc (AccComplAutomaton, Simulation): Rename
to acc_compl_automaton and direct_simulation. At the same time,
reindent the whole file.
* src/sanity/style.test: Detect capitalized class names.
* src/kripke/kripkeexplicit.hh (KripkePrint): Remove useless
predeclaration.
* src/tgbaalgos/simulation.hh: Typo in comment.
* configure.ac: Check for times() and sys/times.h.
* src/misc/timer.hh: Include sys/times.h conditionally
and use clock() if times() is not available.
Reported by Yann Thierry-Mieg.
* src/misc/acccompl.cc, src/misc/acccompl.hh: Add a way to
an acceptance condition in an automaton, into its
complement.
Create a method to make the reverse operation.
* src/misc/Makefile.am: Add the new files to the compilation.
* src/misc/intvcmp2.cc (stream_compression_base::run): Fix a case
where the "id" of the compression to use would be miscalculated,
causing wrong values to be encoded.
* src/tgbatest/intvcmp2.cc: Add this particular test case.
The previous setup failed with clang++ 3.0.
* m4/stl.m4: New file.
* configure.ac: Call AC_HEADER_UNORDERED_MAP,
AC_HEADER_TR1_UNORDERED_MAP, and AC_HEADER_EXT_HASH_MAP.
* src/misc/hash.hh: Include _config.h, and used the
SPOT_HAVE_UNORDERED_MAP, SPOT_HAVE_TR1_UNORDERED_MAP,
or SPOT_HAVE_EXT_HASH_MAP defines to decide which
file to include.
* src/misc/bddalloc.cc (bdd_allocator::initialize): Call
bdd_setmaxincrease(500000), because the default is 50000,
which cause garbage collection to occur too often.
Spot 0.7.1 used to need 190 acceptance conditions to translate the
188 literature formulae. With this patch we are down to 185.
That's not an impressive, but there are only ~20 formulae that
require more than 1 acceptance conditions; hence little room for
improvement.
* src/misc/bddlt.hh (bdd_hash): New function.
* src/misc/accconv.hh, src/misc/accconv.cc: New files.
* src/misc/Makefile.am: Add them.

to record all combination of acceptance conditions occurring in a SCC.
* src/tgbaalgos/scc.hh (scc_map::scc::useful_acc): Update description.
* src/tgbaalgos/sccfilter.cc (scc_filter): Simplify acceptance
conditions that are always implied by another acceptance
conditions. Previously, we only removed acceptance conditions
that where always present in accepting SCCs.
* src/tgbatest/sccsimpl.test: New file.
* src/tgbatest/Makefile.am (TESTS): Add it.
built output.
This is also a step towards better checks for things like
__attribute__ or std::tr1.
* m4/ax_prefix_config_h.m4: New file.
* configure.ac: Call AC_CONFIG_HEADERS and AX_PREFIX_CONFIG_H.
* src/misc/Makefile.am: Install misc/_config.h.

* src/misc/intvcmp2.cc (stream_compression_base::run):
Implement a shift-less encoding for the 1-bit and 3-bit cases.
Also declare offsets as size_t, to help 64-bit compilers.
* src/misc/intvcmp2.cc (int_array_array_compression): Specify full
type of stream_compression_base<int_array_array_compression> in
constructor to please g++ versions <= 4.3.
* src/misc/intvcomp.cc (stream_compression_base::run): Limit
repeatitions to 40, not 42.
(stream_decompression_base::refill): Refill the end of the stream
with 0.
(stream_decompression_base::look_n_bits): Add assertion.
* src/tgbatest/intvcomp.cc: Add a new test case.
* src/misc/intvcomp.cc, src/misc/intvcomp.cc: Add interfaces to
compress vector<int> to vector<unsigned>.
* src/tgbatest/intvcomp.cc: Test them.
* src/sanity/style.test: Refine check to avoid a spurious report.
* iface/dve2/dve2.cc: Adjust to use the new mspool allocator,
and get rid of the std::vector used to store compressed states.
* src/misc/intvcomp.hh: Add an "int* -> int*" interface
in addition to the "int* -> vector<unsigned>*" interface.
* src/tgbatest/intvcomp.cc: Test the two interfaces.
* src/ltlparse/ltlscan.ll: Do not recognize `.' as an AND. Allow
it in atomic propositions.
* src/evtgbaparse/evtgbascan.ll, src/tgbaparse/tgbascan.ll: Accept
`.' in identifiers.
* src/misc/bareword.cc (is_bareword): Accept `.' inside
barewords, so that there is no need to quote `X.Y'.
* src/ltltest/parse.test: Do not use `.' as and operator..
* src/misc/hash.hh (identity_hash): New function.
* src/tgba/tgbaexplicit.hh (tgba_explicit_number): Use
identity_hash<int> instead of std::tr1::hash<int> that does not
exist with g++-3.3.
* src/misc/timer.hh (time_info::running): New attribute.
(time_info::start, time_info::stop): Update and check

another.
