According to Sun, you should expect a small performance =loss= for 64 bit
applications (pointer arithmetic just got more complicated, for
example).  They suggest you only compile 64 bit if you need to address
large in-memory structures and the like, or unless you're running on a
machine who's instruction set is natively 64 bit (SunFire?).
