Description

Could we add support for SLIST_REMOVE_AFTER, which is missing from sys/queue.h in some older OS?

Perhaps, from Apple code: 

#ifndef SLIST_REMOVE_AFTER
#define SLIST_REMOVE_AFTER(elm, field) do {             \
        SLIST_NEXT(elm, field) =                        \
            SLIST_NEXT(SLIST_NEXT(elm, field), field);  \
} while (0)
#endif
