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.
Kill some warnings on Ubuntu.
* src/UserCommandReader.cc (UserCommandInterface): Explicitly
ignore the return code of system() to kill a warning.
* src/TestOperations.cc (generateBuchiAutomaton): Explicitly
ignore the return code of write() to kill a warning.
Fix generation of random formulae on 64bits systems.
* src/main.cc (testLoop): Generate random short ints between 0 and
SHRT_MAX, not between 0 and LONG_MAX. On systems where long ints
are 64bits, LRAND(0,LONG_MAX) was returning a value with the lower
32 bits set to 0, and the latter truncation to short int always
yielded the value 0. Consequently all generated formulae were
identical...
compile with g++-4.3 otherwise.
* src/Ltl-parse.yy (matchCharactersFromStream): Declare the chars
as const to kill a g++ warning.
* src/NeverClaim-parse.yy (yyerror): Declare the error
message as const to kill a g++ warning.
option_map::set): Handle default values.
(anonymous::to_int): Do not print anything.
* src/tgbaalgos/gv04.cc, src/tgbaalgos/gv04.hh,
src/tgbaalgos/tau03.cc, src/tgbaalgos/tau03.hh,
src/tgbaalgos/tau03opt.cc, src/tgbaalgos/tau03opt.hh,
src/tgbaalgos/ce.cc, src/tgbaalgos/ce.hh: Take an option_map in
the constructor.
* src/tgbaalgos/gtec.cc, src/tgbaalgos/gtec.hh: Likewise. Handle
the "poprem", "group", and "shy" options via the option_map.
Supply a couvreur99() wrapper to the shy/non-shy variant.
* src/tgbatest/ltl2tgba.cc, src/tgbatest/randtgba.cc,
iface/gspn/ssp.cc: Adjust.
* src/misc/Makefile.am: Add it.
* src/tgbaalgos/emptiness.cc, src/tgbaalgos/emptiness.hh: Add option
facilities to the classes emptiness_check and emptiness_result
* src/tgbaalgos/magic.cc, src/tgbaalgos/magic.hh,
src/tgbaalgos/se05.cc, src/tgbaalgos/se05.hh: Compute optionnaly
accepting runs from stack.
* src/tgbatest/randtgba.cc: Make this option public.
Convert a formula into a string parsable by Spin.
* src/tgbaalgos/neverclaim.hh, src/tgbaalgos/neverclaim.cc: New files.
Print the never claim in Spin format of a degeneralized TGBA.
* src/tgbaalgos/Makefile.am: Add them.
* src/tgbatest/ltl2tgba.cc: Add the option -N which outputs the
never claim in Spin format of a degeneralized TGBA.
* src/tgbatest/ltl2neverclaim.test: New file.
* src/tgbatest/Makefile.am: Add it.
* src/ObstackAlloc.h: ... this. The problem is that alloc.h is a
system header in g++ < 3.0, and Darwin has a case-insensitive
filesystem. System headers that include alloc.h pick the local
Alloc.h version.
* BuchiAutomaton.h, Configuration.h, DispUtil.cc,
ExternalTranslator.h, FormulaRandomizer.h, Graph.h.in,
LtlFormula.h, Makefile.am, NeverClaimAutomaton.h, PathEvaluator.h,
ProductAutomaton.h, SccIterator.h, SharedTestData.h,
StatDisplay.h, StateSpace.h, StateSpaceRandomizer.cc,
StringUtil.h, TestOperations.h, TestRoundInfo.h, TestStatistics.h,
UserCommandReader.h, UserCommands.h, main.cc: Adjust includes.
and SIGQUIT.
* src/ExternalTranslator.cc (ExternalTranslator::translate): Likewise.
* src/main.cc (main): Do not intercept SIGINT in
non-interactive runs.
