Currently cabextract applies a conditional patch to configure script. This does work, but it's always better to patch configure.ac file instead, and re-run autotools to make sure that it does not get recreated with colliding autotools versions. The attached (simpler) patch removes the check from configure.ac, it can be done unconditionally as it does not create problems to other arches. After that, the ebuild should call eautoreconf (and add inherit autotools) so that the support is recreated. Thanks, Diego
