 Refactoring:
-- create an empty_statement_t and use that instead of a NULL pointer in places
-  like if, loop bodys, statements after labels
 - eliminate target_architecture.h and replace with stuff in lang_features.h
+- create structures for variables and functions, removing the omnipotent
+  declaration
 
 Lexer:
-- Add preprocessor code
+- Add preprocessor code.
 - proper handling of different file encodings, parsing non-ascii strings
 - We could save some space by holding source positions in a separate (somehow
   compressed table) and only storing pointers to it on the AST.
 
 Parser:
-- the expect macros abort functions directly. This leads to some functions
-  not resetting the current context properly (parse_for); expect in expressions
-  suddenly return NULL which triggers asserts
-- label: declaration; is no valid C99 but we parse it anyway
-- designator support for initializers
-- add constant folding code
+- disallow storage class specifiers in struct/union members
+- add constant folding code (optional, ast2firm already does it)
 - Refactor code, so code to handle number values (and strings?) is an own
   module and replacable
 - Support some attributes. noreturn, unused, printf, scanf, packed would be

+Missing Errors:

+* check switches for double cases
 
 Missing Warnings:
 * dead assignments (int x = 5; x = bla(); -> dead assignment at x = 5;)
 * unused label
