TODO

 Critical:
 
-- add structure assign.
-- fix 'char' and 'short' casts.
-- 0 is pointer - fix type compare
-- fix L'' and L"" wide chars
-- add message if external function or variable not found.
-- function pointers to forward reference (patch code generator).
 - add float/double support (should be as small as possible while being
   usable for RISC code generator too).

 Not critical:

+- fix multiple compound literals inits in blocks (ISOC99 normative

+- fix preprocessor symbol redefinition
 - better constant opt (&&, ||, ?:)
 - add ELF executable and shared library output option (would be needed
   for completness!).
