Summary: Math.pow problems

Initial Comment:
Our implementation of Math.pow calls libc pow 
directly. But I found there're times pow doesn't work 
correctly when running JBB2000 with O3.
That is, pow(10.0, -3.0) produces negative infinity. I 
don't know what's the cause. This will happen only 
once, but always repeatable.
Temporarily I use a patch to compare the result, if 
it's abnormal then execute pow again. 
When JBB2000 could run, hope other guys could repeat 
the problem and give a real patch.
