* ldlang.c (load_symbols): Check for archive before object. Use
bfd_check_format_matches, and, if ambiguous, print a list of matching formats. If file format is not recognized, treat file as a linker script. * ldgram.y (yyerror): If assuming an object file is a script, mention that. Tweak the format of the error messages. * ldlex.l (lex_warn_invalid): If assuming an object is a script, guess that this is not actually a script, and just report that the file format was not recognized. * ld.texinfo (Options): Admit that -( may be used more than once. Add note that unrecognized object files are now treated as linker scripts. * ldfile.c (ldfile_input_filename): Make const. (ldfile_assumed_script): New variable. (try_open): Change arguments types to const. (ldfile_find_command_file): Likewise. (ldfile_open_command_file): Likewise. Also, set lineno to 1. * ldfile.h: Update declarations for ldfile.c changes. * ldlex.l: Include <ctype.h>. (file_name_stack): Change to be const char *. (lineno_stack): New static variable. (<<EOF>>): Set lineno as well as ldfile_input_filename. (lex_push_file): Make name argument const. Initialize lineno_stack entry. (lex_redirect): Initialize lineno_stack entry. (lex_warn_invalid): Handle non printable characters nicely. * ldlex.h (lex_push_file): Declare second argument as const. * ldgram.y (ifile_p1): Recognize GROUP. * ldlex.l: Recognize GROUP. * ld.texinfo (Option Commands): Document GROUP.
