[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	//
	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)
[c0aa336]	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]	304	// The grammar in the ANSI C standard is not strictly context-free, since it relies upon the distinct terminal symbols
	305	// "identifier" and "TYPEDEFname" that are lexically identical. While it is possible to write a purely context-free
	306	// grammar, such a grammar would obscure the relationship between syntactic and semantic constructs. Hence, this
	307	// grammar uses the ANSI style.
[c11e31c]	308	//
[de62360d]	309	// Cforall compounds this problem by introducing type names local to the scope of a declaration (for instance, those
[9059213]	310	// introduced through "forall" qualifiers), and by introducing "type generators" -- parameterized types. This latter
[de62360d]	311	// type name creates a third class of identifiers that must be distinguished by the scanner.
[c11e31c]	312	//
[de62360d]	313	// Since the scanner cannot distinguish among the different classes of identifiers without some context information, it
[9059213]	314	// accesses a data structure (TypedefTable) to allow classification of an identifier that it has just read. Semantic
	315	// actions during the parser update this data structure when the class of identifiers change.
[c11e31c]	316	//
[de62360d]	317	// Because the Cforall language is block-scoped, there is the possibility that an identifier can change its class in a
	318	// local scope; it must revert to its original class at the end of the block. Since type names can be local to a
	319	// particular declaration, each declaration is itself a scope. This requires distinguishing between type names that are
	320	// local to the current declaration scope and those that persist past the end of the declaration (i.e., names defined in

	327	// enough context and look-ahead information to decide whether a new scope is necessary, so the effect of these extra
