+Refactoring:
+- eliminate target_architecture.h and replace with stuff in lang_features.h
+- create structures for variables and functions, removing the omnipotent
+  declaration
+
 Lexer:
-- proper support of preprocessor
-- parse float numbers
-- octal&hex escape sequences
-- handling of newline is probably not correct for all strange OSes
+- 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:
+- 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
+  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
+- 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.
+- handle bitfield members with 0 correctly (standard says they finish the
+  current unit)
+- create asm nodes.
+
+Missing Errors:
+* label: declaration; is no valid C99 but we parse it anyway
+* check switches for double cases
+
+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
+  (but some few exceptions like toplevel, nested assignments)
