/* To centralize the declaration of %tokens, their presence in this
file is taken as their declaration. The Makefile will produce
a grammar file (tokenfile.g) from this file.
Moreover, rather than looking up a symbol in all these lists
to find its printable name, a fast version of symbol2str() is
generated from these tables.
Consequenty some of these tables are not referenced explicitly
in the C text any more. To save space and to avoid lint confusion,
these have been made pseudo-invisible by #ifdefs.
