Is it possible to use Bison itself rather than implement the

Guile is also using a translation/reimplementation of Bison in Scheme.
I haven't looked at the CEDET code, but Guile's version wants  the
grammar input using Scheme (s-expression) syntax.

CEDET uses Bison grammars which are extended through "Optional Lambda
Expressions" (OLE). They produce the actual tags, which are the basic
objects resulting from the parsing stage. I don't think this can be
easily replaced by Bison itself or Guile.

Sorry, I didn't mean to suggest replacing it with Guile, more that, if the requirements were similar enough, Bison extensions to support both CEDET and Guile might be possible. But if you're extending the grammar with Lisp code, that may not be feasible....
