This makes cross-compiling happy, use a trick similar to autoconf's AC_CHECK_SIZEOF macro. Basically we make an array: static int array[1 - 2 * !(((long int)(sizeof(off_t))) < 8)]; This gives -1 multiplied by the negation of the condition (sizeof(off_t) < 8) cast to a long int. So if the condition is true it gives array[(-1 * 0)] (remember the condition is cast and negated) thus passing a build test with a 0-sized array. If it's false it gives array[(-1 * 1)] thus failing with a negative-sized array.
