Excellent bits of wisdom .. I agree .. it is just the case that for some
reason the sun compiler does not see that subroutine as "contained" and
ends up creating a library with repeated symbols. A workaround is to use
-z muldefs for linking, which is not recommended as Axel pointed out.

Thanks, L.
