Without dwelling too much on the semantic problem, the answer
to my understanding of your question is: No, there is no C code in the
lars package, but there is a single Fortran routine in the package.
The Fortran routine does not seem to do anything useful in itself.
By the way, the more recent glmnet package by the same authors provides
a faster alternative to lars (for lasso), and it works for glm's too.
