I agree - if FOO is a function-like or complete-statement-like macro than it is
more consistent to expand it to no-op statement than to nothing. (I am not sure if
 the same is true for other type of macros, e.g. expression-like ones).

BTW, I think that this is a very typical practice, many C projects that I worked
on used this convention. Our assert.h also does this.
