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.
* 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.
