These are caused by "-std=iso9899:1990" being used during ./configure, the
conftest programs fail because many linux kernel headers are not ANSI
compliant. We can fix this by passing "--disable-warnings" to ./configure
so that "-std=iso9899:1990" does not get used. This affects many packages,
almost all the KDE packages, and I think MPlayer too, and others. This
also affects all recent kernels (back to 2.4).
