Here is the patch with the docs update.

	* gcc.c (The Specs Language): Document spec functions.
	(INIT_STATIC_SPEC_FUNCTION, static_spec_functions)
	(spec_functions, init_spec_functions, register_spec_function)
	(eval_spec_function, handle_spec_function)
	(if_exists_spec_function, alloc_args): New.
	(execute): Abort if processing_spec_function is true.
	(do_spec_1): Hand off spec to handle_spec_function if %:
	is encountered.  If processing_spec_function is true,
	end any pending argument when the end of the string is reached.
	(main): Call init_spec_functions.  Use alloc_args to allocate
	the initial argument vector.
	* gcc.h (register_spec_function): New prototype.

	* doc/invoke.texi: Document spec functions.

	* config/netbsd-elf.h (STARTFILE_SPEC): Add if-exists(crti%O%s).
	(ENDFILE_SPEC): Add if-exists(crtn%O%s).
	* config/alpha/netbsd.h (ENDFILE_SPEC): Likewise.
