Likewise for me. There are cases when a HAVE_FOO macro needs to be defined to 0 in the negative case (for example, if we want to use it as an expression inside a function). I would prefer not to have to go back to a state where I have to think about each #if: "should I write #if or #ifdef here?" Bruno
