+ lalr1.cc: don't generate location.hh when location_type is defined
+ * data/bison.m4 (b4_percent_define_get): Accept a default value.
+ * data/c++.m4: Do not provide a default value for the %define
+ variable location_type, rather, use b4_percent_define_get with a
+ default argument where its value is needed.
+ * data/lalr1.cc: Do not load location.cc (which outputs both
+ location.hh and position.hh) if the user defined location_type.
+ Do not include location.hh either.
