Using system headers if available seems like a good idea.

What is the difference?  This sounds bad.

If they are unused, we could remove the definitions.

Yes.  Understanding what the differences is, and which one is right, seems useful first though.  If the problem is in gnulib, we can fix that and GnuTLS will have the new variant soon.
