Feature #4644: DateTime.new does not work with Float

When initializing a DateTime object, one can pass seconds as Floats, like 5.5. The decimals get added to sec_fraction. This works great in Ruby 1.9, but not in 1.8.
It fails in Line 527 of the "date.rb":http://redmine.ruby-lang.org/projects/ruby-18/repository/entry/lib/date.rb#L527 with the message "NoMethodError: undefined method `to_r' for 7325.5:Float".

Even more amazing to me, is that you can't pass a DateTime to
DateTime.new,
and the same for Date. Surely you should be able to construct one from
another?

I should probably raise a separate issue for this...?

accepts flonum without Float#to_r.
anyway.
