+
+ A set of fixes for precise line/column location.
+
+ * location.cs :

+ from the segment, and a column number. See also:
+ http://lists.ximian.com/pipermail/mono-devel-list/2004-
+ December/009508.html
+ Removed static IsNull. Use instance IsNull property instead.
+ * cs-tokenizer.cs :
+ For some tokens it stores Location. For Identifier it stores
+ LocatedToken which is a pair of string name and location.
+ Column numbers are adjusted only at getChar().
+ * report.cs :
+ Use Location.ToString() for reporting (it now contains column).
+ * cs-parser.jay :
+ Largely modified to use LocatedToken instead of
+ string (IDENTIFIER), and to acquire Location from some tokens.
+ * namespace.cs, decl.cs, ecore.cs, class.cs, delegate.cs,
+ iterators.cs, const.cs, anonymous.cs, tree.cs, enum.cs,
+ codegen.cs :
+ Now MemberName holds Location. DeclSpace.ctor() receives Location
+ as a parameter. Removed extra parameters to all derived classes.
+ Replaced Location.IsNull() with instance property.
+ * assign.cs, expression.cs :
+ Added .ctor() overload that omits Location.
+ * attribute.cs :
+ Added "nameEscaped" flag that indicates the identifier was escaped
+ in the source file. This fixes bug #57047.

+ - it contains structural changes which are neither mentioned in

+ - structural changes like this should go in in seperate patches
+ and not be hidden in a huge patch which just seems to affect
+ warnings and errors.
+ a big and hard to understand patch.
+ - it breaks iterators and causes regressions, for instance in
+ test-iter-03.cs.

+ flags based on language version.
+ (Expression.Error_UnexpectedKind): Use a simple string array
