Never mind this approach. Now sizeof(foo) is 12 instead of 4 as it was
before, which is probably not acceptable for most applications. I
guess it's either compile without strict compliance or use the
__extension__ workaround and make sure all the compilers you want to
use on your code know what to do. Such a thing as an anonymous struct
simply doesn't seem to exist in the Standard.
The following seems to work with -Wextra -pedantic, although it uses
accessors, which require a lot of changes to the code that uses Coords:
typedef signed short Sint16;
typedef unsigned int Uint32;
struct Coords {
Coords(const int X, const int Y) {parts.x = X, parts.y = Y;}
bool operator<(const Coords other) const {return all < other.all;}
signed short int get_x() const {return parts.x;}
signed short int get_y() const {return parts.y;}
void set_x(const Sint16 X) {parts.x = X;}
void set_y(const Sint16 Y) {parts.y = Y;}
union {
struct {Sint16 x, y;} parts;
Uint32 all;
};
};
