Wouldn't you know it... The one I grabbed (also from the NitrOS9 tree, but 
in a different spot) had zeroes there.  But, interestingly enough, all the 
linker cares about is that the language/type byte not be zero.  Seeing 
that, the linker itself ensures that the correct $11, $81 sequence ends up 
in the generated binary.

Indeed, if you look above that line there's a define for 'Typ' of 1.  By 
making that line

  psect cstart_a,Typ,0,Edit,Stk,_cstart

everything just works fine.

I have it working now.  At least, it's generating what appears to be a 
proper binary.  I'm calling it a day and will try running it on the CoCo 
tomorrow.

At this point, a shell script is working fine as a compiler driver.  I'll 
take a look at that various cc front ends once I know this is all 
operating as planned.

Thanks for all the help, everyone!  Much appreciated.
