This was helpful. I've now replaced -ffreestanding and with GNU Make one can
easily amend the general compilation recipe with extra CFLAGS for specific
files, like so:
memcpy.o memset.o: CFLAGS += -fno-tree-loop-distribute-patterns
$(OBJS): %.o : %.c
$(CC) $(CFLAGS) -c -o $@ $<

This works, too, and I prefer it because the __attribute__ is attached
to the code itself.
Stefan, I received a bounce for my reply to you yesterday:
<stefan@xxxxxxxxx>: host serveronline.org[78.46.86.77] said: 451-sending server

The GNU help mailing list accepted it, though:

Similarly, your reply

wasn't delivered to me.
