-/* Based on:
-ANSI C Yacc grammar
-
-In 1985, Jeff Lee published his Yacc grammar (which is accompanied by a
-matching Lex specification) for the April 30, 1985 draft version of the
-ANSI C standard. Tom Stockfisch reposted it to net.sources in 1987; that
-original, as mentioned in the answer to question 17.25 of the comp.lang.c
-FAQ, can be ftp'ed from ftp.uu.net, file usenet/net.sources/ansi.c.grammar.Z.
-
-I intend to keep this version as close to the current C Standard grammar as
-possible; please let me know if you discover discrepancies.
