These headers include "system.h" which already includes
<new> and <string.h> so including them after "system.h"
is a noop and including them before may cause problems
if they depend on gcc macros from system.h.
ipa-icf-gimple.c includes <list> after system.h which
poisons various libc symbols which may cause problems
and it is not used at all.
Tested together with PATCH 2/2.
OK for trunk?
