- 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
+- redo storage classes: so we can separate real from declared storage class
Lexer:
- Add preprocessor code
compressed table) and only storing pointers to it on the AST.
Parser:
+- disallow storage class specifiers in sturct/union members
- the expect macros abort functions directly. This leads to some functions
not resetting the current context properly (parse_for); expect in expressions
suddenly return NULL which triggers asserts
