Interesting question!  If you have an ANSI CPP, it will take two macros
(here given as STR and QUOTE).

    #define greeting hello Jennifer

    #define STR(x) #x
    #define QUOTE(x) STR(x)

    QUOTE(greeting) will expand to "hello Jennifer"

The ANSI stringization operator stringizes an "unexpanded" actual parameter
list, hence a two-step method is needed to force the expansion.
