4 - eliminate target_architecture.h and replace with stuff in lang_features.h
5 - create structures for variables and functions, removing the omnipotent declaration
8 - Add preprocessor code
9 - proper handling of different file encodings, parsing non-ascii strings
10 - We could save some space by holding source positions in a separate (somehow
11 compressed table) and only storing pointers to it on the AST.
14 - disallow storage class specifiers in struct/union members
15 - label: declaration; is no valid C99 but we parse it anyway
16 - add constant folding code (optional, ast2firm already does it)
17 - Refactor code, so code to handle number values (and strings?) is an own
19 - Support some attributes. noreturn, unused, printf, scanf, packed would be
20 interesting candidates
21 - Add columns to source positions
22 - SourcePositions could be stored selectively on expressions that really need
24 - check semantic for functions declared/defined in global scope and declared
25 again in a local scope
26 - print initialisation type_path for initializer errors
27 - check switches for: double cases, all enums
30 - handle non-constant initializers
31 - output source file positions for panics...
32 - handle bitfield members with 0 correctly (standard says they finish the
36 * check switches for double cases
39 * dead assignments (int x = 5; x = bla(); -> dead assignment at x = 5;)
41 * check switches for all enums values
45 (only test datasets tried yet)
50 186.crafty: works (~though an asm is replaced with a stub)
