Any ideas appreciated.

Something like this (and build with GENERATE_PARSER=1) _ought_ to do it,
but doesn't work:

@@ -269,7 +270,7 @@ cvar_qualifier_seq:

 cvar_qualifier:
 	CONST_KEYW | VOLATILE_KEYW | ATTRIBUTE_PHRASE
-	| RESTRICT_KEYW
+	| RESTRICT_KEYW | EXTENSION_KEYW
 		{ /* restrict has no effect in prototypes so ignore it */
 		  remove_node($1);
 		  $$ = $1;

Well it's actually technically not a cvar_qualifier; it's a pseudo- arbitrarily attached keyword that can be stuck on any number of GCC- only constructs, like nested code: "__extension__ ({ foo(); 1; })" for example.

Probably the simplest thing to do is actually to just convert it into a nonexistent or whitespace token, or if there's a preprocessing step just #define it to the empty string.
