+ * ldlang.h (lang_input_statement_type): Make next
+ and next_real_file a lang_input_statement_type pointer.
+ (lang_statement_append): Delete prototype.
+ (LANG_FOR_EACH_INPUT_STATEMENT): Update for lang_input_statement_type
+ change.
+ * ldmain.c (add_archive_element): Likewise.
+ * ldlang.c: Likewise throughout.
+ (lang_statement_append): Make static. Make element and field
+ void pointers. Remove casts in calls.
+ (lang_check): Use a lang_input_statement_type pointer for "file".
+ (find_rescan_insertion): Similarly for "iter" and return value.
+ (lang_process): Similarly for "insert", "iter" and "temp".
+ * emultempl/spuelf.em (embedded_spu_file): Likewise.
+ * emultempl/aix.em (gld${EMULATION_NAME}_before_allocation): Expand
+ lang_statment_append call.
+
