The compiler might optimize based on our declaration that something is unused. Putting that declaration in the header risks getting out of sync with the actual implementation, so it belongs better only in the .c files. We were mostly compliant, and a new syntax check will help us in the future. * cfg.mk (sc_avoid_attribute_unused_in_header): New syntax check. * src/nodeinfo.h (nodeGetCPUStats, nodeGetMemoryStats): Delete attribute already present in .c file. * src/qemu/qemu_domain.h (qemuDomainEventFlush): Likewise. * src/util/virterror_internal.h (virReportErrorHelper): Parameters are actually used by .c file. * src/xenxs/xen_sxpr.h (xenFormatSxprDisk): Adjust prototype. * src/xenxs/xen_sxpr.c (xenFormatSxprDisk): Delete unused argument. (xenFormatSxpr): Adjust caller. * src/xen/xend_internal.c (xenDaemonAttachDeviceFlags) (xenDaemonUpdateDeviceFlags): Likewise. Suggested by Daniel Veillard.
