libcpp/ChangeLog * include/cpplib.h (struct cpp_dir): Add new field, canonical_name. gcc/ChangeLog * incpath.c: Use HOST_LACKS_INODE_NUMBERS conditional rather than OS names to choose INO_T_EQ definition. (DIRS_EQ) [!INO_T_EQ]: Don't worry about case in comparison. (add_path) [!INO_T_EQ]: Use lrealpath to fill canonical_name field. From-SVN: r136196
