Log Message:
Updated devel/frama-c to its latest version. Changes include:

-! Kernel     [2012/09/17] Remove useless negative options -no-help,
	      -no-version, -no-print-share-path, -no-print-lib-path and
	      -no-print-plugin-path.
o!* Cil       [2012/09/12] Split constants of logic and C (fixes bts #745).
o! Cil        [2012/09/12] Remove type Cil_type.typsig. Use the functions in
	      Cil_datatype.Typ and Cil_datatype.Logic_typ to compare types.
o! Kernel     [2012/09/03] Remove obsolete constructors Cabs.TRANSFORMER and
	      Cabs.EXPRTRANSFORMER and related parsing rules.
o! Value      [2012/08/29] Signature change for function
	      Db.Value.register_builtin: builtins can now return multiple
	      states.
o! Value      [2012/08/20] Rename Db.Value.assigns_to_zone_inputs_state to
	      Db.Value.assigns_inputs_to_zone. Add new functions
	      Db.Value.assigns_outputs_to_zone and
	      Db.Value.assigns_inputs_to_locations.
o!* Kernel    [2012/07/31] Operations that silently mutate AST should now call
	      Ast.mark_as_changed to clear states depending on it
	      (fixes #!1244).
-! Inout      [2012/07/22] Option -inout-callwise restarts Value when it is
	      newly set
o! Cil        [2012/07/16] Ast changed: Unrool_level renamed into Unroll_specs
	      and its argument becomes a list for next evolutions.
o! Kernel     [2012/07/16] Add function [stmt_can_reach] to the arguments
	      of Dataflow.Backwards, which is used to speed up the analysis.
	      See dataflow.mli for good possible values.
-! Rte        [2012/07/16] Rename option -rte-const into
	      -rte-no-trivial-annotations (set by default).
-! Value      [2012/07/12] More thorough checks for calls through a function
	      pointer: warn when the function type and the pointer are
              not compatible, and stop when they cannot be reconciled.
-! Kernel     [2012/07/12] A negative value given to -ulevel option hides all
	      UNROLL_LOOP pragmas.
+! Kernel     [2012/07/10] Change semantics of 'reachable' properties
	      for functions. Use intrinsic notion instead of accessibility
	      of first statement.
o! Kernel     [2012/06/25] Correct (albeit slow) hash function for terms
	      and term lvalues.
-! Kernel     [2012/06/22] improve 'reachable' properties.
o! Kernel     [2012/06/19] Remove module Inthash. Use Datatype.Int.Hashtbl
	      instead, or directly carbon2nitrogen.sh migration script.
o! Value      [2012/06/18] Made type Ival.tt private.
o! Kernel     [2012/06/11] New API for Annotations which merges old
	      Annotations, Globals.Annotations and operations of Kernel_function
	      over function contracts.
-! Pdg        [2012/06/08] Rename option -dot-pdg into -pdg-dot
o! Kernel     [2012/05/30] Kernel.Functions.get does not silently create
	      a kernel function if it does not already exist. This behavior
	      is kept for Cil builtins.
o! Kernel     [2012/04/26] Plugin.set_optional_help is now deprecated.
*! Kernel     [2012/04/14] Introduce more temporaries for a call [lv = f()] if
	      the return type of f and the type of lv do not match. Fix
	      issue #1024.
o! Kernel     [2012/03/26] Kernel.CppExtraArgs now gets type
	      Plugin.String_list and not Plugin.String_set (fixed bts #!1132).
-! Kernel     [2012/02/29] Adding some more supports for built-in related to
	      memory blocks.
-!  Cil       [2012/02/24] Functions returning a value cannot let control flow
	      falling through the closing '}'  Fixes #685.
-! Kernel     [2012/02/23] Sets generated assigns clauses into the default
	      behavior.
-! Kernel     [2012/02/08] Adding supports for clause allocates and frees
              and their version for loops.
o! Value      [2011/12/02] Moved contents of memory_state/Abstract_value
	      into ai/Lattice_Interval_Set. Use bin/nitrogen2oxygen for
	      automatic migration.
-*! Kernel    [2011/11/07] empty list in complete/disjoint is expanded by
	      logic type-checker to the list of behavior name of current
	      contract. Fixes issue #1006. See bts comments for the
	      differences that can appear in the treatment of specs.
o! Cil        [2011/11/04] Add method pFile in printers. Signature change for
	      Cil.d_file (but you should use !Ast_printer.d_file).
o! Kernel     [2011/10/18] Logic_preprocess.file takes an additional parameter,
	      as gcc pre-processor treats differently .c and .cxx files,
	      and this must be reflected in annotation pre-processing.
