I wonder if those changes can be used to get gcc to emit debugging 
information on Apollos as well? I would really love to gcc and 
g++ on apollos with debug information. I'm not familiar with 
Apollo's variety of COFF, but maybe someone who is might be able to 
judge how difficult such a port might be.
