This isn't really a compiler issue.  There is something wrong with your
libraries.  Those libraries did not come from GCC, and I don't know
where they came from.

You can try using the option -Wl, and then looking in the
file to see why the different objects are being included.  That may
suggest how to fix your libraries.
