Doesn't it try to write the object to S:, and the listing to M: ? Neither 
of which probably exist.

I remember the first time I used ZASM (a CP/M Z80 assembler) on an 
RML380Z. I typed 'ZASM FOO,ZSM and got a 'BDOS ERROR ON Z: SELECT' for my 
efforts....

To return to the original question, how far back do you have to go for 
unix's cc(1) to require .c on C source files, .o on object files (to be 
linked it), and so on?
