+ * gfortran.h (gfc_file): Remove sibling and down fields.
+ * scanner.c (file_changes, file_changes_cur, file_changes_count,
+ file_changes_allocated): New variables.
+ (add_file_change, report_file_change): New functions.
+ (change_file): Remove.
+ (gfc_start_source_files, gfc_end_source_files): Call
+ report_file_change instead of change_file.
+ (gfc_advance_line): Call report_file_change instead of change_file,
+ call it even if lb->file == lb->next->file.
+ (get_file): Revert last changes.
+ (preprocessor_line): Call add_file_change when entering or leaving
+ a file.
+ (load_file): Likewise. Set file_change[...].lb for all newly added
+ file changes.
