[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.

	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	//
	33	// 1. nested functions
	34	// 2. generalized lvalues
	35	// 3. designation with and without '=' (use ':' instead)
	36	// 4. attributes not allowed in parenthesis of declarator
	37	//
[de62360d]	38	// All of the syntactic extensions for GCC C are marked with the comment "GCC". The second extensions are for Cforall
	39	// (CFA), which fixes several of C's outstanding problems and extends C with many modern language concepts. All of the
	40	// syntactic extensions for CFA C are marked with the comment "CFA". As noted above, there is one unreconcileable
	41	// parsing problem between C99 and CFA with respect to designators; this is discussed in detail before the "designation"
	42	// grammar rule.

[de62360d]	254	// The grammar in the ANSI C standard is not strictly context-free, since it relies upon the distinct terminal symbols
	255	// "identifier" and "TYPEDEFname" that are lexically identical. While it is possible to write a purely context-free
	256	// grammar, such a grammar would obscure the relationship between syntactic and semantic constructs. Hence, this
	257	// grammar uses the ANSI style.
[c11e31c]	258	//
[de62360d]	259	// Cforall compounds this problem by introducing type names local to the scope of a declaration (for instance, those
	260	// introduced through "forall" qualifiers), and by introducing "type generators" -- parametrized types. This latter
	261	// type name creates a third class of identifiers that must be distinguished by the scanner.
[c11e31c]	262	//
[de62360d]	263	// Since the scanner cannot distinguish among the different classes of identifiers without some context information, it
	264	// accesses a data structure (the TypedefTable) to allow classification of an identifier that it has just read.
	265	// Semantic actions during the parser update this data structure when the class of identifiers change.
[c11e31c]	266	//
[de62360d]	267	// Because the Cforall language is block-scoped, there is the possibility that an identifier can change its class in a
	268	// local scope; it must revert to its original class at the end of the block. Since type names can be local to a
	269	// particular declaration, each declaration is itself a scope. This requires distinguishing between type names that are
	270	// local to the current declaration scope and those that persist past the end of the declaration (i.e., names defined in
	271	// "typedef" or "type" declarations).
[c11e31c]	272	//
[de62360d]	273	// The non-terminals "push" and "pop" derive the empty string; their only use is to denote the opening and closing of
	274	// scopes. Every push must have a matching pop, although it is regrettable the matching pairs do not always occur
	275	// within the same rule. These non-terminals may appear in more contexts than strictly necessary from a semantic point
	276	// of view. Unfortunately, these extra rules are necessary to prevent parsing conflicts -- the parser may not have
	277	// enough context and look-ahead information to decide whether a new scope is necessary, so the effect of these extra
	278	// rules is to open a new scope unconditionally. As the grammar evolves, it may be neccesary to add or move around
