Xen devel - Aug 2012 - /usr/src/new/xen-unstable.hg/tools/qemu-xen-dir/fpu/softfloat-specialize.h:92: error: initializer element is not constant

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:

Thx !
