Description:
------------
When running the bitwiseNot_basiclong_64bit.phpt test on ppc64, the output 
differs 
in one place from the expected results.  This seems to be a result of MAX_64Bit 
+ 
1 being internally interpreted as a float and some kind of rounding error, 
however I'm not certain that is the case.  The failing test is the third from 
the bottom in the output.

I originally found this in 5.3.2 on RHEL 6, but I built a local 5.3.6 and it 
happens there still as well.
