Fix for PR gdb/209, PR gdb/156:
* gdbarch.c, gdbarch.h: Rebuilt. * gdbarch.sh: Added `construct_inferior_arguments'. * cli/cli-decode.h (cmd_list_element): Added pre_show_hook. Typo fix. * cli/cli-setshow.c (do_setshow_command): Call the pre_show_hook. * infcmd.c (_initialize_infcmd): Set sfunc on `set args' command. (inferior_argc, inferior_argv): New globals. (notice_args_set): New function. (set_inferior_args): Clear inferior_argc and inferior_argv. (set_inferior_args_vector): New function. (get_inferior_args): Handle inferior argument vector. (run_command): Use get_inferior_args(). (notice_args_read): New function. (_initialize_infcmd): Don't call set_inferior_args. * command.h: Typo fix. (cmd_list_element): Added pre_show_hook. * main.c (captured_main): Added --args option. (print_gdb_help): Document --args. * inferior.h (construct_inferior_arguments): Declare. (set_inferior_args_vector): Likewise. * fork-child.c (construct_inferior_arguments): New function.
