[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.

[dd54139]	26	// The root language for this grammar is ANSI99/11 C. All of ANSI99/11 is parsed. Most of the syntactic extensions from
	27	// ANSI90 to ANSI11 C are marked with the comment "C99/C11".
[f9c3100]	28
[e16eb460]	29	// This grammar also has two levels of extensions. The first extensions cover most of the GCC C extensions. All of the
[9380add]	30	// syntactic extensions for GCC C are marked with the comment "GCC". The second extensions are for Cforall (CFA), which
	31	// fixes several of C's outstanding problems and extends C with many modern language concepts. All of the syntactic
	32	// extensions for CFA C are marked with the comment "CFA".

[3d26610]	631	// While it may be possible to write a purely context-free grammar, such a grammar would obscure the relationship

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

[c11e31c]	636	//
[3d26610]	637	// Since the scanner cannot distinguish among the different classes of identifiers without some context information,
