3// Tacent platform defines, architecture, and endianness detection. The Tacent library has some preprocessor define 
4// requirements. One of PLATFORM_NNN, ARCHITECTURE_NNN, and CONFIG_NNN need to be defined. If you haven't bothered 
5// to define these in the project file with a /D switch, an attempt is made to define them automatically for you.
