diagnostic.c: Don't include opts.h.

Browse Source 
* diagnostic.c: Don't include opts.h.
	(permissive_error_option): Define.
	(diagnostic_initialize): Take n_opts parameter.  Allocate memory
	for classify_diagnostic.  Don't use memset for
	classify_diagnostic.  Initialize new and recently added fields.
	(diagnostic_classify_diagnostic): Use context->n_opts instead of
	N_OPTS.
	(diagnostic_report_diagnostic): Pass context parameter to
	diagnostic_report_warnings_p.  Use option_enabled and option_name
	hooks from context.
	(emit_diagnostic): Use permissive_error_option.
	(permerror): Likewise.
	* diagnostic.h: Don't include options.h.
	(struct diagnostic_context): Add n_opts, opt_permissive,
	inhibit_warnings, warn_system_headers, option_enabled and
	option_name fields.  Change classify_diagnostic to a pointer.
	* opts-diagnostic.h: New file.
	* opts.c: Include opts-diagnostic.h.
	(common_handle_option): Set global_dc fields for -Wfatal-errors,
	-Wsystem-headers, -fshow-column, -pedantic-errors and -w.
	(option_name): New function.
	* c-opts.c (c_common_init_options): Set global_dc->opt_permissive.
	(c_common_handle_option): Set global_dc->permissive for
	-fpermissive.
	* c-common.c (c_cpp_error): Save and restore
	global_dc->warn_system_headers, not variable warn_system_headers.
	* toplev.c: Include opts-diagnostic.h.
	(general_init): Update call to diagnostic_initialize.  Set
	global_dc->show_column, global_dc->option_enabled and
	global_dc->option_name.
	(process_options): Don't set global_dc fields here.
	* Makefile.in (DIAGNOSTIC_H): Remove options.h.
	(diagnostic.o, opts.o, toplev.o): Update dependencies.

fortran:
	* cpp.c (cb_cpp_error): Save and restore
