Agreed, hence my question if there's a reason for the duplicate definition. I'm guessing it just never tripped an error, though.

There's your explanation (from `man gcc`):
           Loads all members of static archive libraries.  See man ld(1) for more information.

Now the question is of course, do *you* need that option, linking what appears to be an executable?
