The most important for me are:

- missing yacc, lex rules (with the same strict check as in the autoconf
  build)

- waf build should (by default )give an error if a reconfigure.
  optional auto reconfigure isn't strictly needed.
  If we don't add that, developers could get to a stage (after a git
  pull) where the 'waf build' and 'make' will just display a very
  confusing error, which they don't now how to handle without a
  git clean -x -d -f or waf distclean (I guess waf clean would not
  help).

I think we need to at least maintain it until waf has fixed the missing
features.
