The Linux kernel takes it a step farther: #define BIT(nr) (1UL << (nr)) #define BIT_MASK(nr) (1UL << ((nr) % BITS_PER_LONG)) #define BIT_WORD(nr) ((nr) /

Hacks like these make unfamiliar code quite hard to understand (I'm looking at you OpenCV).

  Yeah. It gets easier to understand once you use ctags/etags to have a "go to definition" key while you're hovering over a symbol.
