From: Hans de Goede <hdegoede@xxxxxxxxxx> With gcc-7.1.1 I was getting the following compile error: error: ‘*’ in boolean context, suggest ‘&&’ instead The problem is the definition of CEIL_DIV: #define CEIL_DIV(a, b) ((b) ? ((a) + (b) - 1) / (b) : 0) Which when called as: CEIL_DIV(x, y * z) triggers this error, note we cannot do as the error suggests since b is evaluated multiple times. This commit fixes these compile errors.
