 * OS and architecture. In any case, failure to detect the architecture
 * as 64-bit means that the 32-bit code will be used, and that code
 * works also on 64-bit architectures (the 64-bit code may simply be
 * more efficient).
 *
 * The test on 'unsigned long' should already catch most cases, the one
 * notable exception being Windows code where 'unsigned long' is kept to
 * 32-bit for compatibility with all the legacy code that liberally uses
 * the 'DWORD' type for 32-bit values.
 *
 * Macro names are taken from: http://nadeausoftware.com/articles/2012/02/c_c_tip_how_detect_processor_type_using_compiler_predefined_macros
