I wrote a cross compiler for parallel C (running on a PC) at the university of 
Stuttgart.

The point is: I do not know about the status of the basis of this work, Johnsons 
Portable-C-Compiler for the PDP-11. Until I know more, I cannot say whether it 
is available or not.

This is *impossible*. OCCAM does not allow neither recursion nor dynamic memory 
management (heap) nor pointer types not structure/union types.

PAR, ALT, i/o and timer operations are included.
