Definitely. But constant expressions are evaluated at compile time. So the dead branch (if or else) doesn't generate any object code. There is no memory footprint overhead. When possible, I prefer to use C conditionals rather than preprocessor conditionals. I raised the point because I see u-boot wants to get rid of preprocessor mess when it brings no cost. /alessandro ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
