[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.

[de62360d]	23	// Acknowledgments to Richard Bilson, Glen Ditchfield, and Rodolfo Gabriel Esteves who all helped when I got stuck with
	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.

[3d26610]	481	// The C grammar is not context free because it relies on the distinct terminal symbols "identifier" and "TYPEDEFname",

[3d26610]	487	// While it may be possible to write a purely context-free grammar, such a grammar would obscure the relationship
	488	// between syntactic and semantic constructs. Cforall compounds this problem by introducing type names local to the
	489	// scope of a declaration (for instance, those introduced through "forall" qualifiers), and by introducing "type
	490	// generators" -- parameterized types. This latter type name creates a third class of identifiers, "TYPEGENname", which
	491	// must be distinguished by the lexical scanner.
[c11e31c]	492	//
[3d26610]	493	// Since the scanner cannot distinguish among the different classes of identifiers without some context information,
	494	// there is a type table (typedefTable), which holds type names and identifiers that override type names, for each named
	495	// scope. During parsing, semantic actions update the type table by adding new identifiers in the current scope. For
	496	// each context that introduces a name scope, a new level is created in the type table and that level is popped on
	497	// exiting the scope. Since type names can be local to a particular declaration, each declaration is itself a scope.
	498	// This requires distinguishing between type names that are local to the current declaration scope and those that
