------- Comment #7 from jsm28 at gcc dot gnu dot org 2005-11-01 00:25 ------- diagnostic.c gets #include stack information from input_file_stack. cpplib gets it from source_locations. With --enable-mapped-location, this regression could be fixed by diagnostic.c getting it from source_locations as well.
