You might want to try:
http://www.mathsoft.co.uk/splus/download/cfortran.pdf
There is an example in there which is reasonibly clear.
The c/fortran bit of glm code in Splus, uses some special magic stuff with
frames and memcpys. I've got some example code of that here is that might
be a better type of solution. Although I have try this stuff in R, and it
might not work.
