A macro definition has to consist of a sequence of tokens.  A string
constant (sequence of characters enclosed in double quotes) is a token,
but the double quote by itself is not.

If you are trying to construct strings containing macro defs, look at
the stringize operator (#) and token merge operator (##)in the
preprocessor documentation.
