I do not understand what the -s is doing here.

the file you need to specify in the "as" clause of the define function 
command must be a shared library in 4.2/SunOS4.x. This extra step generates
the shared library (since -Bdynamic is the default) and call it "foo.o".

your observation is correct. circle.o is not a shared library and is not
ready for dynamic loading.

Thanks-- vital info.
