[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.

	26	// The root language for this grammar is ANSI99/11 C. All of ANSI99/11 is parsed, except for:
	27	//
	28	// 1. designation with '=' (use ':' instead)
	29	//
[de62360d]	30	// Most of the syntactic extensions from ANSI90 to ANSI11 C are marked with the comment "C99/C11". This grammar also has
	31	// two levels of extensions. The first extensions cover most of the GCC C extensions, except for:
[c11e31c]	32	//
[e7aed49]	33	// 1. designation with and without '=' (use ':' instead)
	34	// 2. attributes not allowed in parenthesis of declarator
[c11e31c]	35	//
[de62360d]	36	// All of the syntactic extensions for GCC C are marked with the comment "GCC". The second extensions are for Cforall
	37	// (CFA), which fixes several of C's outstanding problems and extends C with many modern language concepts. All of the
	38	// syntactic extensions for CFA C are marked with the comment "CFA". As noted above, there is one unreconcileable
	39	// parsing problem between C99 and CFA with respect to designators; this is discussed in detail before the "designation"
	40	// grammar rule.

[de62360d]	277	// The grammar in the ANSI C standard is not strictly context-free, since it relies upon the distinct terminal symbols
	278	// "identifier" and "TYPEDEFname" that are lexically identical. While it is possible to write a purely context-free
	279	// grammar, such a grammar would obscure the relationship between syntactic and semantic constructs. Hence, this
	280	// grammar uses the ANSI style.
[c11e31c]	281	//
[de62360d]	282	// Cforall compounds this problem by introducing type names local to the scope of a declaration (for instance, those
[9059213]	283	// introduced through "forall" qualifiers), and by introducing "type generators" -- parameterized types. This latter
[de62360d]	284	// type name creates a third class of identifiers that must be distinguished by the scanner.
[c11e31c]	285	//
[de62360d]	286	// Since the scanner cannot distinguish among the different classes of identifiers without some context information, it
[9059213]	287	// accesses a data structure (TypedefTable) to allow classification of an identifier that it has just read. Semantic
	288	// actions during the parser update this data structure when the class of identifiers change.
[c11e31c]	289	//
[de62360d]	290	// Because the Cforall language is block-scoped, there is the possibility that an identifier can change its class in a
	291	// local scope; it must revert to its original class at the end of the block. Since type names can be local to a
	292	// particular declaration, each declaration is itself a scope. This requires distinguishing between type names that are
	293	// local to the current declaration scope and those that persist past the end of the declaration (i.e., names defined in

[c11e31c]	295	//
[de62360d]	296	// The non-terminals "push" and "pop" derive the empty string; their only use is to denote the opening and closing of

	300	// enough context and look-ahead information to decide whether a new scope is necessary, so the effect of these extra
	301	// rules is to open a new scope unconditionally. As the grammar evolves, it may be neccesary to add or move around

[c11e31c]	1821	//
	1822	// Overloading: function, data, and operator identifiers may be overloaded.
	1823	//
[de62360d]	1824	// Type declarations: "type" is used to generate new types for declaring objects. Similarly, "dtype" is used for object
	1825	// and incomplete types, and "ftype" is used for function types. Type declarations with initializers provide
	1826	// definitions of new types. Type declarations with storage class "extern" provide opaque types.
[c11e31c]	1827	//
[de62360d]	1828	// Polymorphic functions: A forall clause declares a type parameter. The corresponding argument is inferred at the call

[c11e31c]	1830	//
	1831	// Specifications and Assertions: Specifications are collections of declarations parameterized by one or more
[de62360d]	1832	// types. They serve many of the purposes of abstract classes, and specification hierarchies resemble subclass
	1833	// hierarchies. Unlike classes, they can define relationships between types. Assertions declare that a type or
	1834	// types provide the operations declared by a specification. Assertions are normally used to declare requirements
