> decaf::lang::Long::to{Hex,Binary,Octal}String return the wrong result for
> numbers less than -2^32 (on platforms with 64 bit long long): the returned
> string only represents the low 32 bits.
> A separate problem causes decaf::lang::{Integer,Long}::toOctalString to
> return the wrong result for negative numbers because there are not an even
> multiple of 3 bits.
> This test program demonstrates the problems
> $ cat test.cpp
