The difference is that with -E the -o option is passed to cc1, whereas

using the last -o option.
Nevertheless it might be a good idea to file a bug for binutils.
Consistency is probably more important, and it helps in case of typos.
In this case, I don't think consistency should win over maintaining
long-established behaviour. I'm more inclined to say that cc1 should change
to follow long-established *nix tradition. (I have absolutely found it useful
on at least one occasion to be able to add a -o option into CFLAGS and know it
would come last on the command-line and win.)
Hello
Would it be useful to have an option to enable warning if there are
duplicates?
From my point of view, I feel that not warning duplicates may let
mistakes in the way gcc is invoked slip through, e.g. assist tracking
down these issues in makefiles.
Best regards, Jon
