2 - Rename type_string to type_char_ptr
3 - Rename the statement_base_t statement; field in all the statements to
7 - Add preprocessor code
8 - proper handling of different file encodings, parsing non-ascii strings
11 - the expect macros abort functions directly. This leads to some functions
12 not resetting the current context properly (parse_for)
13 - label: declaration; is no valid C99 but we parse it anyway
14 - designator support for initializers
15 - add constant folding code
16 - Refactor code, so code to handle number values and strings is
17 an own module and replacable
18 - Support some attributes. noreturn, unused, printf, scanf, packed would be
19 interesting candidates
22 - output source file positions for panics...
23 - output variable names for uninitialized variable warnings
26 * dead assignments (int x = 5; x = bla(); -> dead assignment at x = 5;)
