When sign-imag-errp is false, I think $sign shouldn't
signal an error for a nonreal argument. But ...

(defun $gr (a b)
(let ((sign-imag-errp nil))
(eq t (mgrp a b))))

(%i107) gr(5,%i);
Maxima encountered a Lisp error: Error in LET [or
callee]: The tag SIGN-IMAG-ERR is undefined.

    Without looking at the code, I am inclined to agree that
    SIGN-IMAG-ERRP should quiet SIGN-IMAG-ERR.
