 709     Stringify macros to process raw text passed via -D options to C string constants. The double-wrapping is necessary
 710     because the C preprocessor doesn't perform its normal argument expansion pre-scan with stringified macros so the
 711     -D macro needs to be expanded once via the wrapper macro then stringified so the raw text is stringified. Otherwise,
 712     the replacement value would be used instead of the symbolic name (only for preprocessor symbols like #defines).
 713
 714     For example:
 715
 716  #define        kMyConstant             1
 717
 718         printf( "%s", Stringify( kMyConstant ) );                       // Prints "kMyConstant"
 719         printf( "%s", StringifyExpansion( kMyConstant ) );      // Prints "1"
 720
 721     Non-preprocessor symbols do not have this issue. For example:
 722
 723         enum
 724         {
 725             kMyConstant = 1
 726         };
 727
 728         printf( "%s", Stringify( kMyConstant ) );                       // Prints "kMyConstant"
 729         printf( "%s", StringifyExpansion( kMyConstant ) );      // Prints "kMyConstant"
 730
 731     See <http://gcc.gnu.org/onlinedocs/cpp/Argument-Prescan.html> for more info on C preprocessor pre-scanning.
