Qemu-dm compiling error with SDL

[Thomas Goirand <thomas@goirand.fr>]

Doing the following:

cp -f /usr/share/misc/config.sub .
cp -f /usr/share/misc/config.guess
./configure --audio-drv-list="oss alsa sdl pa esd" \
--audio-card-list="ac97 es1370 sb16 cs4231a adlib gus" --enable-mixemu
$(MAKE) install DESTDIR=debian/$(PKG_NAME)

generates the following error:

  CC    sdl.o
sdl.c: In function ‘sdl_update_caption’:
sdl.c:499: error: ‘domain_name’ undeclared (first use in this function)
sdl.c:499: error: (Each undeclared identifier is reported only once
sdl.c:499: error: for each function it appears in.)
make[1]: *** [sdl.o] Error 1
make[1]: Leaving directory `/usr/src/xen/xen-qemu-dm-3.4'
make: *** [install] Error 2
dpkg-buildpackage: failure: fakeroot debian/rules binary gave error exit
status 2

this did NOT happen with the Debian source package from Bastian, and it
still does this when I apply the debian/patches from him So I'm
wondering what's going on here. Does anyone know? Note that this happens
in both Lenny and SID.
