I basically need to give yyparse a few extra parametres, move all local 
variables of that functions into a parameter passed structure, initiate the 
structure on the first call and change references from local variables to the 
corresponding structure elements.

I do not know m4 well yet, so my first question is: From the maintainers point 
of view, is it better to patch yacc.c or start with a new file, say 
yacc_push.c (and yacc_push.h)?
