/****************************************************************************************************

    TARGET_CPU_*    
    These conditionals specify which microprocessor instruction set is being
    generated.  At most one of these is true, the rest are false.

        TARGET_CPU_PPC          - Compiler is generating PowerPC instructions for 32-bit mode
        TARGET_CPU_PPC64        - Compiler is generating PowerPC instructions for 64-bit mode
        TARGET_CPU_68K          - Compiler is generating 680x0 instructions
        TARGET_CPU_X86          - Compiler is generating x86 instructions
        TARGET_CPU_ARM          - Compiler is generating ARM instructions
        TARGET_CPU_MIPS         - Compiler is generating MIPS instructions
        TARGET_CPU_SPARC        - Compiler is generating Sparc instructions
        TARGET_CPU_ALPHA        - Compiler is generating Dec Alpha instructions


    TARGET_OS_* 
    These conditionals specify in which Operating System the generated code will
    run. The MAC/WIN32/UNIX conditionals are mutually exclusive.  The EMBEDDED/IPHONE 
	conditionals are variants of TARGET_OS_MAC. 

        TARGET_OS_MAC           - Generate code will run under Mac OS
        TARGET_OS_WIN32         - Generate code will run under 32-bit Windows
        TARGET_OS_UNIX          - Generate code will run under some non Mac OS X unix 
        TARGET_OS_EMBEDDED      - Generate code will run under an embedded OS variant
                                  of TARGET_OS_MAC
        TARGET_OS_IPHONE        - Generate code will run under iPhone OS which 
                                  is a variant of TARGET_OS_MAC.

    TARGET_RT_* 
    These conditionals specify in which runtime the generated code will
    run. This is needed when the OS and CPU support more than one runtime
    (e.g. Mac OS X supports CFM and mach-o).

        TARGET_RT_LITTLE_ENDIAN - Generated code uses little endian format for integers
        TARGET_RT_BIG_ENDIAN    - Generated code uses big endian format for integers    
        TARGET_RT_64_BIT        - Generated code uses 64-bit pointers    
        TARGET_RT_MAC_CFM       - TARGET_OS_MAC is true and CFM68K or PowerPC CFM (TVectors) are used
        TARGET_RT_MAC_MACHO     - TARGET_OS_MAC is true and Mach-O/dlyd runtime is used


    TARGET_IPHONE_SIMULATOR     - Generate code for running under iPhone Simulator
