/* 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.
|
