Andrew: my understanding of Bruce's proposal is that the strdup() name 
will now be kept (in this case through an inline definition), so I think 
this will be ok.  However, your comment reminded me of something else 
that it's probably worth mentioning as an aside:

As a general guideline on Windows, memory allocated within a shared 
library is best freed within the same DLL to ensure it goes back to the 
correct heap.  So we'd want to avoid calling strdup and then returning 
the value to the application for it to free (hopefully this doesn't 
happen). With an inline definition there's no change in behaviour, but 
adding rte_strdup (or anything else that calls malloc) into librte_eal 
might be an issue.
