Thanks. It was not entirely clear even after re-reading the manual. But after 
some considerations, it makes sense to just define a new typedef.

AFAICT, the locations are only used in the YYLLOC_DEFAULT macro, and then as a 
dummy parameter to yysymprint. It would of course be quite nice to include 
the location information as well. Beside hacking the skeleton files, is there 
any official way, I can redefine yysymprint or the macro YYDSYMPRINT?

Are there any particuliar reasons for concern when using the location tracking 
?
Or is nobody actually using this feature ?
