- emul-i386:
  - running without tracing, maybe with trapping, just mmap, execute
    and setting the stack (simple loader), maybe binfmt-compatible?
- asm-i386:
  - device a new version which runs on c4 and is again freestanding   
  - extend the opcodes slightly so we can use our current generator
    (and not the old inefficient stack machine)
- c4/cc:
  - function forward definitons
  - checkout c5-AST branch
  - inline assembly
  - void parameter declaration for functions like f(void) instead of f()
  - global char array declarations: instead of char *buf, malloc(512) we could
    use char buf[512]
  - static: just ignore, we don't have a linker, otoh, just rewrite it whithout static,
    vararg, etc. so the code will later respect local definitions of functions.
    do not allow non-reentrant f() { static var; } constructs.
  - volatile: we are not doing any optimizations for now, so volatile (as const)
    can just be a ignored keyword.
  - void * allowing to omit (char *) from and to for instance structs
    in dynamic memory management
