Given that the origin of the problem is that somehow preprocessing
makes white space get 'inserted' before the actual value of #define'd
symbol and given that macro CURL_CHECK_DEF is used in other places, I
believe that your second option fix is the way to go.

Have you concluded where does the extra white space come from? Is it
actually the preprocessor or something else?
