Thanks. How can I make LD emit these symbols? I need to determine the
size of the image because I need to know how much to lead from the
boot media.

FYI, after reading your mail, I switched the order of .bss and
.data. This seems to have forced ld to reserve the space for .bss
within my output image, and I now have the behavior I want. Are there
any problems with having .bss between .text and .data?
