/*

    DEV_NOTE: Most area's of the Omni framework only ever need to see if we
    are in a Windows based build or *nix/POSIX based environment. In some
    areas we do need to check for other OS's, for example, stopwatch needs
    Apple detection on top of *nix/Win and the non portable code for
    application (see application.cpp) heavily relies on this.
    
    Please note that just because a specific macro is defined below, does not
    mean the framework has been tested to work in that environment. OMNI_OS_OS400
    will be defined, for instance, if the __OS400__ macro is defined (usually by
    the compiler), but this does not mean we have been able to test/build the
    framework in a direct (or even emulated) IBM OS/400 environment.
    
    That being said, the purpose of this file is to give helper macro's for
    possible OS detection, keyword being possible. Should a need ever arise
    to force the Omni framework to build for a separate platform (building
    a POSIX compliant program under Cygwin/MinGW for instance), one can
    define the OMNI_OS_IGNORE preprocessor define and specify which ever
    platform they wish.
