NWR04B: So that's what PC is set to

Finally figured out two things:

1. The macros debug_reloc_start and debug_reloc_end in head.S are not called by default -- which is why I haven't been seeing any output from them. Duh.
2. If I put them in and close a comment properly, I can print out pc -- which as near as I can figure is set to 0x1008 more than it should be if the image was being run from the beginning of memory.

Currently trying a truly horrible hack (.rept 4112 instead of .rept 8 at the beginning of the image) to see what heppens.
