Redifining yyltype

[Henrik Sorensen]

Hello List,

What is the recommended way to redefine the structure used for tracking token 
locations?

Should I define a new typedef or redefine the yyltype ?
Or something else I didn't think of ?

1) 
  typedef myOwnLtype { .... } myOwnLtype;
  #define YYLTYPE myOwnLtype
or
2)
  typedef yyltype { int a;int b; } yyltype;
...

please cc me, as I am not subscribed to help-bison

Thanks

Henrik
