 Refactoring:
 - 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.
@@ -15,42 +12,28 @@ Parser:
 - 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
-  interesting candidates
 - Add columns to source positions
 - SourcePositions could be stored selectively on expressions that really need
   them.
 - check semantic for functions declared/defined in global scope and declared
   again in a local scope
+- for errors relating to function argument, print number of argument
 - print initialisation type_path for initializer errors
-- check switches for: double cases, all enums
 
 ast2firm:
-- handle non-constant initializers
-- output source file positions for panics...
+- output source file positions for panics.
 - handle bitfield members with 0 correctly (standard says they finish the
   current unit)
 
 Missing Errors:
-* label: declaration; is no valid C99 but we parse it anyway
-* check switches for double cases
+- goto over VLA declarations
 
 Missing Warnings:
-* dead assignments (int x = 5; x = bla(); -> dead assignment at x = 5;)
-* unused label
-* check switches for all enums values
-* catch the if(k = b) cases, maybe require all assignments to be in parentheses
+- dead assignments (int x = 5; x = bla(); -> dead assignment at x = 5;)
+- catch the if(k = b) cases, maybe require all assignments to be in parentheses
   (but some few exceptions like toplevel, nested assignments)
