+Initializer rewrite:
+- determining of array size for array types of unspecified length is wrong in
+  presence of designators and unions
+
+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
+
 Lexer:
-- proper support of preprocessor
-- parse float numbers
-- octal&hex escape sequences
-- wide string constants
-- proper handling of different file encodings
+- 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)
-- proper handling of function pointer types
-- outermost typequalifiers can differ between function declarations and
-  implementations...
-- fix semantic to ignore type qualifiers (const double is the same as double)
+  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
+- 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
 
 ast2firm:
+- handle non-constant initializers
 - output source file positions for panics...
-- correctly handle pointer ++, --
+- handle bitfield members with 0 correctly (standard says they finish the
+  current unit)
+
+Missing Warnings:
+* dead assignments (int x = 5; x = bla(); -> dead assignment at x = 5;)
+* unused label
+*
