	* c-pch.c (pch_ready_to_save_cpp_state, pch_cpp_state_saved)
	(pch_cpp_save_state): New.
	(pch_init): Call pch_cpp_save_state conditionally, instead of
	calling cpp_save_state.

	gcc.dg/cpp/mi5.c, gcc.dg/cpp/multiline.c: Add -nostdinc to
	dg-options.

libcpp:
	* files.c (struct _cpp_file): Add implicit_preinclude.
	(pch_open_file): Allow a previously opened implicitly included
	file.
	(_cpp_find_file): Add implicit_preinclude argument.  Free file and
	do not call open_file_failed if implicit_preinclude.  Store
	implicit_preinclude value.
	(_cpp_stack_include, _cpp_fake_include, _cpp_compare_file_date):
	Update calls to _cpp_find_file.
	(_cpp_stack_include): Handle IT_DEFAULT.
