+
+ * cpplib.h (parse_underflow_t, CPP_NULL_BUFFER): Delete.
+ (struct cpp_buffer): Remove fname and underflow fields.
+ (struct cpp_reader): Remove get_token field.
+ (struct include_hash): Rename to struct ihash. Add typedef to
+ IHASH.
+ (struct if_stack): Remove fname field.
+ (IF_STACK_FRAME): Rename to IF_STACK.
+
+ * cpperror.c (print_containing_files): Trust that there are no
+ macro buffers below the top file buffer.
+ * cppfiles.c: Replace all references to 'struct include_hash'
+ with 'IHASH'. Rename initialize_input_buffer to
+ init_input_buffer. Don't set or reference cpp_buffer->fname,
+ use buffer->ihash->name instead.
+ * cpphash.c (special_symbol): Use cpp_file_buffer. Use NULL
+ not CPP_NULL_BUFFER.
+ * cppinit.c: Use NULL not CPP_NULL_BUFFER, IF_STACK not
+ IF_STACK_FRAME, IHASH not struct include_hash.
+ * cpplib.c: Rename eval_if_expression to eval_if_expr. Remove
+ null_underflow. Use IF_STACK not IF_STACK_FRAME, IHASH not
+ struct include_hash, NULL not CPP_NULL_BUFFER. Remove all
+ references to cpp_buffer->fname (delete entirely, or use
+ ->ihash->name instead) and IF_STACK->fname.
+ (cpp_push_buffer): Don't set new->underflow.
+ (do_include): Use cpp_file_buffer.
+
+ * cpphash.c (collect_formal_parameters): Remove duplicate
+ increment of argslen. Pedwarn in C99 mode if __VA_ARGS__ is
+ used as a macro argument name. Don't append "..." to namebuf
+ for varargs macros. After we're done scanning, go through
+ namebuf and make it NUL separated, not comma separated.
+ (_cpp_compare_defs): Remove register tag from variables.
+ Expect defn->argnames to be NUL separated.
+ (_cpp_dump_definition): Expect defn->argnames to be NUL
+ separated and in forward order.
+ * cpphash.h: Update documentation of argnames field.
