I haven't seen the C and Fortran code for Random Forest but I understand the note to say that R code calls some C functions that pre-process (possibly re-format etc) the data, then call the actual Random Forest method that's written in Fortran, then possibly post-process the output and return it to R. It would imply that to understand the actual Random Forest code, you will have to read the Fortran source code.
