Flavio Ceolin 4eb3db13bc sys: util: Add macro to declare flexible arrays ... Flexible arrays are arrays declared without a specific size, e.g: uint8_t my_array[]; They are widely used as as last member in structs that are dynamically allocated. Since C99 they are part of the C standard, but for historical reasons many places still use an older GNU extension that is declare zero length arrays. Although zero length arrays are flexible arrays, we can't blindly replace [0] with [] because of some syntax limitations. This macro workaround these limitations while get rid of this non standard extension. Using true flexible arrays allows the compiler to calculate the size of the array better and improve potential issue checking.
