* symbol.c : Add gfc_global_ns_list.
* decl.c (add_global_entry): Set the namespace ('ns') field.
* gfortran.h : Add the resolved field to gfc_namespace. Add the
namespace ('ns') field to gfc_gsymbol. Add flag_whole_file to
gfc_option_t. Add the prototype for gfc_free_dt_list.
* lang.opt : Add the whole-file option.
* invoke.texi : Document the whole-file option.
* resolve.c (resolve_global_procedure): If the fwhole-file
option is set, reorder gsymbols to ensure that translation is
in the right order. Resolve the gsymbol's namespace if that
has not occurred and then check interfaces.
(resolve_function): Move call to resolve_global_procedure.
(resolve_call): The same.
(resolve_codes): Store the current labels_obstack.
(gfc_resolve) : Return if the namespace is already resolved.
trans-decl.c (gfc_get_extern_function_decl): If the whole_file
option is selected, use the backend_decl of a gsymbol, if it is
available.
parse.c (add_global_procedure, add_global_program): If the flag
whole-file is set, add the namespace to the gsymbol.
(gfc_parse_file): On -fwhole-file, put procedure namespaces on
the global namespace list. Rearrange to do resolution of all
the procedures in a file, followed by their translation.
* options.c (gfc_init_options): Add -fwhole-file.
(gfc_handle_option): The same.
