typedef needs to issue a deprecation error when used in D2.

Shouldn't we provide a complete library based typedef first? http://d.puremagic.com/issues/show_bug.cgi?id=5467

I think it is better to catch this in the parser stage, rather than semantic.


--- Dsymbols *Parser::parseDeclarations ---
             if (tok == TOKtypedef)
+            {
+                if (!global.params.useDeprecated)
+                    error("typedef is deprecated, use alias");
                 v = new TypedefDeclaration(loc, ident, t, init);
+            }

Iain

Wouldn't this prevent using typedef even inside version(none) etc blocks?  Is
that something we want?
