(I'm not sure -R is the right name for the relocation switch;  maybe
Guy Harris can help me out here.  The loader has a switch to set the start
address;  it's used in building the Unix kernel.  Go look at the makefile
for the Unix kernel;  it makes use of the switch to relocate the kernel to
hex 2400 or some such offset.)
