This part of the warning is due to a bug in the darwin configuration files:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30572

I've been ignoring the warning without problems, but a workaround is
to use the option "-Wl,-dylib_file,/libgcc_s.1.dylib:<your gcc install
path>/lib/libgcc_s.1.dylib"

Try that, and see if the warning goes away.
