#4242 STYLE-WARNING in share/contrib/diffequations/odelin.lisp

[David Billinghurst]

Originally reported by Richard Gobeli as a follow-up to bug [#4184] bessel_simplify error. Broken out to a new bug as not related.

I have a work file that when loading contrib_ode I get thses warnings.
My work sheet uses N,Q,V, and X.
I don't know, if the intenal variables will affect or be affected by the external variables.

(%i405) load( "contrib_ode");

Unsure which lisp is giving this error. The code in question is around line 663 of https://sourceforge.net/p/maxima/code/ci/master/tree/share/contrib/diffequations/odelin.lisp

(defun hypergeo21-xi-denom-filter (n)
  (declare (ignore n))
  0)

(defun hypergeo21-xi-degree-bound (q v x)
  (declare (ignore q v x))
  1)

I think it's SBCL which generates warnings like that; I've tagged it accordingly. If that's not right, we'll just change the tag.
