Strictly speaking, we should test the processor architecture
rather than the OS to determine the byte order, because an OS
may support processors with different byte orders.

Common predefined macros for processor architectures
currently or soon to be supported by V8:
GCC: __i386__, __x86_64__, __arm__ (__ARMEL__ or __ARMEB__)
Visual C++: _M_IX86, _M_X64 (older form _M_AMD64)

Nit: use <stdlib.h> for a system header.  You may want to
combine this with line 65 above.
