/* 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.
Jutta Degener, 1995
