[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.
[c11e31c]	22
[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	//
[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]	578	// The C grammar is not context free because it relies on the distinct terminal symbols "identifier" and "TYPEDEFname",

[3d26610]	584	// While it may be possible to write a purely context-free grammar, such a grammar would obscure the relationship

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

[c11e31c]	589	//
[3d26610]	590	// Since the scanner cannot distinguish among the different classes of identifiers without some context information,

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

	3914	// ISO/IEC 9899:1999 Section 6.7.5.3(11) : "In a parameter declaration, a single typedef name in

	3924	// int g( int g1( T g2( int p ) ) ); // see identifier_parameter_declarator
	3925	//
	3926	// In essence, a '(' immediately to the left of typedef name, T, is interpreted as starting a parameter type list, and
