I checked in the attached patch.  It fixes some problems caused by
initialization and option processing happening in the wrong order.

	* c-objc-common.c (init_c_objc_common_once):  Move INIT_STATEMENT_CODES
	to here from init_c_objc_common_eachsrc.

	* c-objc-common.c (init_c_objc_common_eachsrc):  Move call to
	c_decl_processing_eachsrc before cpp_do_macro_callbacks, since
	before does reset_cpp_hashnodes and so would undo latter.
	
	* c-opts.c (finish_options):  Move cpp_find_main_file call out to
	c_common_post_options.
	(c_common_post_options):  Call finish_options only if preprocess-only.
	(init_c_common_eachsrc):  Call finish_options here instead.
	This is because we want to process the command-line after
	reset_cpp_hashnodes, not before.
