The parse function now catches exceptions, uses the %destructors to
release memory (the lookahead symbol and the symbols pushed on the stack)
- before rethrowing the exception.

This feature is somewhat experimental. User feedback would be
appreciated.
"function declared 'noreturn' should not return") have also been
addressed.

+** New %define variable: api.location.type (glr.cc, lalr1.cc, lalr1.java)
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
under the name "location_type" (which is maintained for backward
compatibility).
+ For consistency, lalr1.java's %define variables location_type and
+ position_type are deprecated in favor of api.location.type and
+ api.position.type.

* Noteworthy changes in release 2.6.2 (2012-08-03) [stable]
