* Doing two levels allows the parameter to be a macro itself.
|
|
* For example, compile with `-DFOO=bar`, `STRINGIFY(FOO)` converts to "bar".
|
|
*
|
|
* \param x will be converted to one string, including the spaces and commas
|
|
* between arguments. For example `STRINGIFY( a , b )` will be expanded to "a
|
|
* , b".
