I believe this is an issue in gnulib, because the relevant autoconf
detection code, as well as the replacement implementation that fails to
compile on OpenIndiana, are imported from gnulib.

I've CC'd the bug-gnu...@gnu.org mailing list, for input from the gnulib
developers.

Thanks for this report,

      Mark
