+
+	selinux-h: Make generated .h files standalone.
+	* lib/se-context.in.h: Arrange to include _GL_UNUSED_PARAMETER
+	definition. Use _GL_UNUSED_PARAMETER instead of _GL_UNUSED.
+	* lib/se-selinux.in.h: Likewise.
+	* modules/selinux-h (Depends-on): Add unused-parameter.
+	(Makefile.am): Insert definition of _GL_UNUSED_PARAMETER into
+	selinux/selinux.h and selinux/context.h.
+	Suggested by Eric Blake.
+
 2009-12-25  Bruno Haible  <bruno@clisp.org>
 
 	Move gl_FCNTL_O_FLAGS to a separate .m4 file.
