Hi All,

I'm was trying to compile xen-unstable (last changeset: 25786) and ran into a compile error in qemu-xen:

After freshly cloning, running ./configure and make world:

Hello Olaf,

Ahh yes good point, after setting them for a kernel build, i had set them to "", instead of unsetting them completely ...

Thx !
