Greetings!  Is there a reason that maxima instructs GCL alone to use
denormalized numbers in the f2cl stuff?

(defun d1mach (i)
  (ecase i
     #-gcl least-positive-normalized-double-float
     #+gcl least-positive-double-float)
    (2 most-positive-double-float)
    (3 double-float-epsilon)
    (4 (scale-float double-float-epsilon 1))
    (5 (log (float (float-radix 1d0) 1d0) 10d0))))

This will force -mieee-with-inexact on the alpha architecture, which
slows the code considerably.

Take care,
