Read up on 'pragma No_Run_Time'. It's labeled obsolescent, so apparently
there's a better way to do the same thing.

I'm not clear what you mean by "no header". 

You need some way to load the code into the processor. I assume you are
first writing a boot prom, which will then load the rest of the code. So
you need a tool that will translate the object file into hex for a prom
burner. Gnu binutils must have that somewhere.
