Here's a possibility which is slightly ugly, as all the others are, but the ugliness is in a different place. Write: #ifdef DEBUG #define debug(a) debug_ a #else #define debug(a) #endif Now, write your debug statements with an extra pair of parentheses: debug((x, y, z, ...)); I'm not necessarily recommending this; it's just an idea.
