+       lalr1.cc: don't generate location.hh when location_type is defined
+       * data/bison.m4 (b4_percent_define_use): New.
+       (b4_percent_define_get): Use it.
+       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.
+       * data/glr.cc: Likewise.
