Another story in the saga of portability.. 

My Lisp application calls a C univariate root-finder.
The application works under AKCL or Lucid on sun4s/sparcs, 
but not under AKCL on an SGI Personal Iris. 

Under AKCL, I do:
(defentry c-realroots (int string) (string "CRealRoots"))

where CRealRoots is a C function that takes an integer
representing the degree of a polynomial, and a string
encoding its coefficients, and returns a string
encoding the coefficients. This is all standard KCL;
but it fails on a personal iris (AKCL v. 1.313).

Does anyone know the correct way of compiling and loading
in C code into a running AKCL on a Personal Iris ?
