To make these checks less noisy, add pointer friendly > bitop macros that also do some typechecking to sanitize the argument. Would this work? #define BIT_OP(val, op) ((typeof (val))((unsigned long)(val) op)) Should let you do: ptr = BIT_OP(ptr, | 1); ptr = BIT_OP(ptr, & ~1); if (BIT_OPT(ptr, & 1)) ...
