But it doesn't help us with versioning on platforms that
don't use GNU ld right?  So we have to go through all the hoops
of maintaining backwards compatibility (compatible DSO files).
So what I'm missing is that this seems to make those platforms
the corner cases which means they are guaranteed to break.
My have to support two solutions at all ?

What amI missing here?
