I just set up a build for powerpc with WITHOUT_CLANG and in the first building steps I saw this. I don't care if it is only a few minutes of building time, but I disagree if it is going to be > 10 minutes/hours in case of multilib builds (32-bit libs and 64-bit libs) as it is on powerpc64. On powerpc64 the WITHOUT_CLANG helped to avoid the build of the multilib. I do not have anything against CLANG. I only want to be able to steer what I want. Gruss, Andreas
