I don't know where you get this impression, my impression is entirely
different. I have been doing embedded real time development since 1984,
and find that every compiler uses COFF ever so slightly differently. In
fact, COFF is *intended* to be used that way. It has a special section
devoted to stuff the compiler wants to put in there, whatever it may
be. At least one GCC port I know of put all the program code into that
special section, and left the regular text section empty.

I'm glad to see that you're not just a stander by looking on and
complaining. I think it is admirable what Ullrich has done.

I can explain it for you, but I can't understand it for you.
