[de62360d]	16	// This grammar is based on the ANSI99/11 C grammar, specifically parts of EXPRESSION and STATEMENTS, and on the C
	17	// grammar by James A. Roskind, specifically parts of DECLARATIONS and EXTERNAL DEFINITIONS. While parts have been
	18	// copied, important changes have been made in all sections; these changes are sufficient to constitute a new grammar.
	19	// In particular, this grammar attempts to be more syntactically precise, i.e., it parses less incorrect language syntax
	20	// that must be subsequently rejected by semantic checks. Nevertheless, there are still several semantic checks
	21	// required and many are noted in the grammar. Finally, the grammar is extended with GCC and CFA language extensions.

	24	// the grammar.
[c11e31c]	25
	26	// The root language for this grammar is ANSI99/11 C. All of ANSI99/11 is parsed, except for:
	27	//
[9380add]	28	// designation with '=' (use ':' instead)
[c11e31c]	29	//
[9380add]	30	// This incompatibility is discussed in detail before the "designation" grammar rule. Most of the syntactic extensions
	31	// from ANSI90 to ANSI11 C are marked with the comment "C99/C11".
[f9c3100]	32
[e16eb460]	33	// This grammar also has two levels of extensions. The first extensions cover most of the GCC C extensions. All of the
[9380add]	34	// syntactic extensions for GCC C are marked with the comment "GCC". The second extensions are for Cforall (CFA), which
	35	// fixes several of C's outstanding problems and extends C with many modern language concepts. All of the syntactic
	36	// extensions for CFA C are marked with the comment "CFA".

[3d26610]	524	// While it may be possible to write a purely context-free grammar, such a grammar would obscure the relationship

	527	// generators" -- parameterized types. This latter type name creates a third class of identifiers, "TYPEGENname", which

[c11e31c]	529	//
[3d26610]	530	// Since the scanner cannot distinguish among the different classes of identifiers without some context information,

	533	// each context that introduces a name scope, a new level is created in the type table and that level is popped on
	534	// exiting the scope. Since type names can be local to a particular declaration, each declaration is itself a scope.

[de62360d]	3035	// The following sections are a series of grammar patterns used to parse declarators. Multiple patterns are necessary
	3036	// because the type of an identifier in wrapped around the identifier in the same form as its usage in an expression, as
	3037	// in:
[c11e31c]	3038	//
[b87a5ed]	3039	// int (*f())[10] { ... };
	3040	// ... (*f())[3] += 1; // definition mimics usage
[c11e31c]	3041	//
[de62360d]	3042	// Because these patterns are highly recursive, changes at a lower level in the recursion require copying some or all of
	3043	// the pattern. Each of these patterns has some subtle variation to ensure correct syntax in a particular context.

[de62360d]	3685	// This pattern parses a new-style declaration of an abstract variable or function prototype, i.e., there is no
	3686	// identifier to which the type applies, e.g.:
[c11e31c]	3687	//
[b87a5ed]	3688	// [int] f( int ); // abstract variable parameter; no parameter name specified
	3689	// [int] f( [int] (int) ); // abstract function-prototype parameter; no parameter name specified
[c11e31c]	3690	//
	3691	// These rules need LR(3):
	3692	//
[c0aa336]	3693	// cfa_abstract_tuple identifier_or_type_name
[40de461]	3694	// '[' cfa_parameter_list ']' identifier_or_type_name '(' cfa_parameter_ellipsis_list_opt ')'
[c11e31c]	3695	//

[b87a5ed]	3698	// [int, int] t;
	3699	// [int, int] f( int );

	3703	// lookahead. To accomplish this, cfa_abstract_declarator has an entry point without tuple, and tuple declarations are
