Use the libcc.fs C bindings to call your C program.  You don't need actual 
primitives for that.  Gerald Wodni's fork of SWIG can parse your .h file, and 
generate those bindings for you.

You need to link your program with a switch that it exports dynamic functions 
(like a shared library), to make this work.
