+/* String macros are normally handled quite well by the LALR(k) technique,
+ * but sometimes it's not enough. For instance with 'XX YY', it could
+ * be considered as a declaration with XX being a typedef, so we would
+ * have an ambiguity. So by adding a few special cases (e.g. KERN_WARNING
+ * for the linux kernel), we can catch more string-macros. The idea is
+ * that we need to have at least one witness, a string to recognize
+ * a sequence of strings.

+/* EX_TABLE & co. 
+ *
+ * Replaced by a string. We can't put everything as comment
+ * because it can be part of an expression where we wait for
+ * something, where we wait for a string. So at least we 
+ * must keep the EX_TABLE token and transform it as a string.
+ *
+ * normally not needed if have good stringification of macro 
+ * but those macros are sometimes used multiple times 
+ * as in EX_TABLE(0b) EX_TABLE(1b)  and we don't detect
+ * it well yet.
