The code would do "if (x & 0)" or alike, so I'm not sure this won't 
result in a warning. But as soon as that thing compiles, I don't really 
care much. If it produces no warning, in fact, the code could be 
optimized away out thanks to "& 0".

Just looked up those defs in the debian code search, only lirc and 
v4l-utils care about the defines. ANd the latter seems to define their 
own copies.
