"function declared 'noreturn' should not return") have also been
addressed.
+** New %define variable: api.location.type (glr.cc, lalr1.cc)
+
+ The %define variable api.location.type defines the name of the type to use
+ for locations. When defined, Bison no longer generates the position.hh
+ and location.hh files, nor does the parser will include them: the user is
+ then responsible to define her type.
+
+ This can be used in programs with several parsers to factor their location
+ and position files: let one of them generate them, and the others just use
+ them.
+
+ This feature was actually introduced, but not documented, in Bison 2.5,
+ under the name "location_type" (which is maintained for backward
+ compatibility).
+
* Noteworthy changes in release 2.6.2 (2012-08-03) [stable]
** Bug fixes
