xfst and lexc are proprietary. Xerox does not release the source.
They put a lot of  work into optimizations such as compressing the
compiled transducers and consider the greater speed and smaller
footprint a selling point. However, although I am a fan of free
software (in fact, the Xerox tools are the only
non-free software that I use), I doubt very much that anyone would
have a need to modify xfst or lexc since they are general purpose
tools. 

For non-commercial purposes they can be obtained cheaply as they
come on a CD with the book _Finite State Morphology_.
