[Nicolas Vollmar]

I had tried to compile 2.5.1-pre6 and have got this error:

setup.c: In function `setup_arch':
setup.c:806: `rd_image_start' undeclared (first use in this function)
setup.c:806: (Each undeclared identifier is reported only once
setup.c:806: for each function it appears in.)
setup.c:807: `rd_prompt' undeclared (first use in this function)
