Rob Landley, and others. Currently CONFIG options are defined or undefined, so we chop out code with #ifdefs, ala: #ifdef CONFIG_THING stuff(); #endif This creates a new header file, bb_config.h, which sets the CONFIG entry to 1 or 0, and lets us do: if(CONFIG_THING) stuff(); And let the compiler do dead code elimination to get rid of it. (Note: #ifdef will still work because for the 1 case it's a static const int, not a #define.)
