I think you'll find that doesn't work very well; the script will need at
least some understanding of the bison %-declarations, and it can just
ignore everything else before %%. The reason is that (1) you're going
to need to alter the %type declarations and (2) you're going to need to
merge these declarations with ones from ecpg.
It might be that the merging is best handled via directive-like
comments, but I suspect they'll be in the ecpg-side file not in the
main grammar: you'll have something indicating "insert all the main
%type declarations here", one for "insert precedence declarations
here", etc.
But of course this is just speculation...
