Both of those headers are part of the XSI extension.  The spec states
that a conforming XSI application "shall define _XOPEN_SOURCE to be
600 before any header is included".  The statement in the warning is
thus correct.  Shouting about it seems a bit excessive though,
especially for a distro shipping a broken C compiler.
