Subject: float allocator

I have been testing ruby 1.8 on my windows box before I dare adopt it on 
my linux box. I came across this odd difference:

In ruby 1.6 I can dup a Float:

$ ruby -v
ruby 1.6.8 (2002-12-24) [i586-linux-gnu]
$ irb
irb(main):001:0> a = 3.14
=> 3.14
irb(main):002:0> a.dup
=> 3.14

In ruby 1.8 I cannot:

$ ruby -v
ruby 1.8.1 (2003-12-25) [i386-cygwin]
$ irb
irb(main):001:0> a = 3.14
=> 3.14
irb(main):002:0> a.dup
NoMethodError: allocator undefined for Float
         from (irb):2:in `dup'
         from (irb):2

I did a bit of testing and found out that neither Fixnum, Float or 
Bignum can be dup'ed. Is this intentional, and if so then how do I go 
about copying the descendents of Numeric?
