They're both equally correct, as are all other possible combinations
of hardware (MIPS, Intel, AMD, Sparc, HP, IBM, Cray), operating system
(IRIX, Solaris, Linux, BSD, OSX), compiler version, compiler &
optimization options, c/fortran/assembly inner loops, libc version,
use of math libraries & versions, etc.
