Use getopt instead of lex and yacc to parse the command line. * ld.texinfo (Options): Document changes to option syntax. * Makefile.in: Update dependencies. * ldver.c (help): Tweak dashes in usage message. * ldgram.y (%union): Remove unused members. Remove %tokens for command line options; add ones for input types. (command_line): Rules removed. (file): Instead of command line, recognize an input type indicator, then use the nonterminal for that type. (defsym_expr): New nonterminal from code formerly in command_line. * ldlex.h: Declare parser input type enum and variable. Don't declare parse_line. * ldlex.l: Remove unused variables. Make some used ones static and comment them. (COMMAND): Start state and its rules removed. At start of yylex, return input state token if at start of input. (lex_redirect): Don't need to set yyout. (ldlex_command): Function removed. * ldmain.c (main): Instead of calling parse_line, set up the redirections and call yyparse directly. * ldmisc.c (vfinfo): If there's no input filename, print nothing, not "command line". * lexsup.c: Remove #if 0'd code. (parse_line): Function removed. (parse_args): Rewrite to use getopt_long_only. (set_default_dirlist): New function from code formerly in ldgram.y:command_line.
