Boisy, et al,

I was able to hack one together by taking cstart.a from the CoCo compiler 
and and os9defs.a I found in the NitrOS9 distribution.  I actually had to 
ensure that the C library came last:

$ rlink hello.r cstart.r -l=/dd/lib/clib.l -o=hello

Now, on to the code generation issues.  I cannot see anything in the 
compiler sources that would properly set the psect pseudo-op to the 
correct language/type value.  The compiler has a line that hard-codes zero 
for this value and the following one in the header.

Unless I edit by hand, the linker complains:

linker fatal: 'hello.r' contains no mainline

>From reading the code, this is based on the fact that it's finding zero as 
the language/type value.

In a "real" situation, do you know what modifies the psect line for the 
primary program?
