 That's a bogus warning resulting from unability (despite all the casts) 
to tell GCC that expression is really meant and known to be always true.  
I think it's actually been discussed at the GCC list already; if the 
warning doesn't disappear with 4.1 or so, then it's worth filing a bug 
report at gcc.org.

 Otherwise it's safe to be ignored -- the code produced is correct.
