I am writing a parser where I for reasons of clarity would like to
refer to a given construct by one token name in one context and by
another name in another context, e g use the token name INT for [0-9]+
in one place and NUMBER in another.

Basically I would like to just stick in a =

#define NUMBER INT

somewhere, but bison doesn't like this at all. Neither was I allowed to
%token INT 4711 NUMBER 4711

Of course I could just have a flag and let yylex return one or the
other depending on the flag, but I was hoping there would be a more
elegant way. Suggestions?

and just return INT in the lexer. -John]
