-- Preprocessor: the preprocessor tokens are the same as C. It means
-  that in some rare cases, preprocessed numbers are not handled
-  exactly as in ANSI C. This approach has the advantage of being
-  simpler and FAST!
-
-- Types: floating point numbers are not supported yet.
-
-- Bit fields are not supported.
-
-- Linking: extern variables must appear in a referenced dll and cannot
-  appear in current source.
-
-Supported ANSI C extensions:
----------------------------
-
-- 'inline' keyword is ignored (ISOC99).
-
-- 'restrict' keyword is ignored (ISOC99).
-
-- '__func__' is a string variable containing the current function name (ISOC99).
-
-- Variadic macros: __VA_ARGS__ can be used for function-like macros (ISOC99):
-   #define dprintf(level, __VA_ARGS__) printf(__VA_ARGS__).
-
-- Declarations can appear anywhere in a block (ISOC99).
-
-- Array and struct/union elements can be initialized in any order by
-  using designators (.e.g. { [0].x = 1 }) (ISOC99).
-
-- Compound initializers are supported (e.g. int *p = (int []){ 1, 2,
-  3}) (ISOC99).
-
-- '#!' at the start of a line is ignored to allow scripting.
-
-- Binary digits can be entered ('0b101' instead of '5').

TODO

 TODO list:
 
 Critical:
-
-- add float/double support (should be as small as possible while being
-  usable for RISC code generator too).
+- finish float/double support. add function type convertion.
+- section generation and GNUC __attributte__ handling.
+- D option with '=' handling
 - 0 is pointer - fix type compare
-- add message if external function or variable not found.
 - To check: 'sizeof' may not work if too complex expression is given.
-- fix 'char' and 'short' casts (in function parameters and in assignment).
-- function pointers to forward reference (patch code generator).
+- fix 'char' and 'short' casts (only in function parameters and in
+  assignment).
 
 Not critical:
 
+- interactive mode
 - fix multiple compound literals inits in blocks (ISOC99 normative
   example - only relevant when using gotos! -> must add boolean
   variable to tell if compound literal was already initialized).
-- fix L"\x1234" wide string case (need to store them as ints ?) */
+- fix L"\x1234" wide string case (need to store them as utf8 ?)
 - fix preprocessor symbol redefinition
 - better constant opt (&&, ||, ?:)
 - add ELF executable and shared library output option (would be needed
