+ of errors in the documentation in this regard).
+
+ * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
+
+ * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
+ of these procedures are passed a function call that already has
+ build-in-place actuals (testing new flag
+ Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
+ the case where processing continues.
+ (Expand_Call): If the call is generated from a thunk body then we
+ propagate the extra actuals associated with the accessibility
+ level of the access type actuals.
+
+ * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
+ of each extra formal of a protected operation to reference the
+ corresponding extra formal of the subprogram denoted by the
+ operation's Protected_Body_Subprogram.
+
+ * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
+ N_Function_Call nodes.

+
+ * sem_util.adb (Is_Preelaborable_Expression): New function to determine

+ requires preelaborable init.
+ (Check_Components): Replace inline code that does partial checking for
+ preelaborable default expressions with call to
+ Is_Preelaborable_Expression.
+ (Has_Preelaborable_Initialization): In the case of a generic actual

+
+ * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a

+ (Is_Leap): Move the routine to the scope of Week_In_Year.
+ (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
+ weekday on which January 1 falls of Year - 1 and Year + 1. This function
+ avoids calling Time_Of and Split, thus making it more efficent.
+ (Week_In_Year): Reimplemented in oder to follow ISO 8601.
+
+ * g-calend.ads (Week_In_Year): Change comment to reflect new

+
+2007-09-26 Emmanuel Briot <briot@adacore.com>
+
+ * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
+ Command_Line): New types
+ (Define_Alias, Define_Prefix, Free): New subprograms. These provide
+ support for defining how switches can be grouped on a command line (as
+ is the case for -gnatw... for GNAT), and how simple switches can be
+ used as aliases for more complex switches (-gnatwa is same as
+ -gnatwbcef...)
+ (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
+ (Start, Current_*): New subprograms
+ Added support for parsing an array of strings in addition to the real
+ command line.
+ (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
+ be moved from the body to the private part of the spec.
+ (*): All subprograms now have an extra parameter with default value to
+ specify which parser should be used. For backward compatibility, it
+ defaults to parsing the command line of the application. They were also
+ modified to properly handle cases where each of the argument does not
+ start at index 1 (which is always true for Ada.Command_Line, but not
+ when processing any Argument_List).
+ (Free): New subprogram
+ (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
+ Argument): New subprograms
+ (Switch_Parameter_Type): New enum, which clarifies the code. The extra
+ special characters like ':', '=',... are now handled in a single place,
+ which makes the code more extensible eventually.
+ (Getopt, Full_Switch): When the switch was returned as part of the
+ special character '*', make sure it is prepended by the switch character
+ ('-' in general), so that the application knows whether "foo" or "-foo"
+ was specified on the command line.
+
+2007-09-26 Florian Villoing <villoing@adacore.com>
+
+ * g-dirope.adb (Remove_Dir): In case we are removing directories
+ recursively, make sure that if an exception is raised during the
+ processing, the current working directory is reset to its initial
+ value before propagating the exception.

+ (Side_Effect_Free): A selected component of an access type that

+ (Expand_Subtype_From_Expr): For limited objects initialized with build
