I could put #ifdef HAVE_OPEN_MEMSTREAM around it if that would be less
weird? I'd have thought that _GNU_SOURCE was going to be ignored on
any non-GNU system and so would be harmless.

That define is the only step I know of for pulling in the prototype
(other than explicitly writing the prototype) and I can't think how
any configure test could more directly test for it.
