QEMU-Xen build failure

[Tamas K Lengyel <tamas@xxxxxxxxxxxxx>]

Hi all,
on a recent checkout of the Xen staging source I ran into the
following build error with QEMU upstream:

tools/qemu-xen-dir-remote/slirp/src/ip_input.c:330:5: error: ISO C90
forbids mixed declarations and code
[-Werror=declaration-after-statement]
     int delta = (char *)q - (m->m_flags & M_EXT ? m->m_ext : m->m_dat);
