+ * archive.cc (Library_base::should_include_member): Pull in object
+ from archive if it defines the entry symbol.
+ * parameters.cc (Parameters::entry): New function.
+ * parameters.h (class Parameters): Declare entry.
+ * output.h (class Output_file_header): Remove entry_ field.
+ * output.cc (Output_file_header::Output_file_header): Remove entry
+ parameter. Change all callers.
