strange all.equal() behavior

["Mann, Brad" <Brad.Mann@citadelgroup.com>]

Hello.  I'm running S-Plus 6.0, rel 4 on NT. When I try  

   all.equal( 8, 4 )

I get the correct answer of a 50% relative difference, but when I try

   all.equal( as.single(8) , 4 )

I get the seemingly incorrect and certainly unintuitive value T.  
Is this a bug, or are there some subtleties with int/single/double's 
and all.equal()? Thanks for any info,

Brad
