      Description

      The basic tests TestFloatingRem, TestSerialization and TestMath are failing on my laptop for the configurations "prototype.default" and "development.Opt_1" with the reason "Expected and actual output have different checksums". This happens for Jikes RVM 3.1.0 as well as revision 15829 development.Opt_1.

            Newer versions of gcc apparently optimize well enough that we don't get the necessary drop in precision from 80->64 bits, confusing a loop responsible for converting double/float values to strings.
