State-Changed-When: Sun Dec 15 10:55:46 2002
State-Changed-Why:
    First half (denorm_min()), already fixed for 3.3, it isn't
    a regression and probably the fix will not be backported
    to 3.2.x. Second half (is_iec559), confirmed everywhere as
    a bug in my reading (see 18.2.1.2, 53 and 18.2.1.5, 1),
    easy to patch as soon as the mainline reopens.
