	gcc            : ChangeLog cppexp.c cpphash.h cpplex.c cpplib.c 
	                 cpplib.h cppmacro.c 

Log message:
	* cppexp.c: Don't worry about pfile->skipping.
	* cpplib.c (struct if_stack): Make was_skipping unsigned char.
	(cpp_handle_directive): Save pfile->skipping in struct cpp_buffer
	for handled directives.
	(skip_rest_of_line): Use _cpp_lex_token after popping contexts
	and releasing lookaheads.
	(do_ifdef, do_ifndef, do_if): Use buffer->was_skipping.
	(do_else, do_elif, push_conditional): Update logic.
	(do_endif): Set buffer->was_skipping rather than pfile->skipping.
	(unwind_if_stack): Inline into cpp_pop_buffer.
	(cpp_push_buffer): Clear ifs->was_skipping for cpp_handle_directive.
	* cpplex.c (_cpp_lex_token): Clear skipping on EOF.  Handle
	multiple-include optimisation.
	* cpplib.h (struct cpp_buffer): New member was_skipping.
	* cppmacro.c (_cpp_get_token): Loop whilst pfile->skipping.  This
	works because skipping == 0 in directives.
	(_cpp_release_lookahead): Renamed from release_lookahead.
	(cpp_get_token): No need to check skipping as _cpp_get_token does
	this for us.  No need to handle MI optimisation.
