671 Stringify macros to process raw text passed via -D options to C string constants. The double-wrapping is necessary
672 because the C preprocessor doesn't perform its normal argument expansion pre-scan with stringified macros so the
673 -D macro needs to be expanded once via the wrapper macro then stringified so the raw text is stringified. Otherwise,
674 the replacement value would be used instead of the symbolic name (only for preprocessor symbols like #defines).
675
676 For example:
677
678 #define kMyConstant 1
679
680 printf( "%s", Stringify( kMyConstant ) ); // Prints "kMyConstant"
681 printf( "%s", StringifyExpansion( kMyConstant ) ); // Prints "1"
682
683 Non-preprocessor symbols do not have this issue. For example:
684
685 enum
686 {
687 kMyConstant = 1
688 };
689
690 printf( "%s", Stringify( kMyConstant ) ); // Prints "kMyConstant"
691 printf( "%s", StringifyExpansion( kMyConstant ) ); // Prints "kMyConstant"
692
693 See <http://gcc.gnu.org/onlinedocs/cpp/Argument-Prescan.html> for more info on C preprocessor pre-scanning.
