try this one:
int a, b, c, d;
d = min( a, min( b, c ));
and you will see a gnu c warning about multiple const qualifiers.
(this might depend on the warning level you drive.)
fix it with this code:
#define min(x,y) ({ \
const typeof(x) _x = (x); \
const typeof(y) _y = (y); \
(void) (&_x == &_y); \
(_x < _y) ? (typeof(x)) _x : (typeof(y)) _y; })
simply the last line has changed towards linux kernel patch-2.4.10-pre9 from
ftp.
the same change should apply for the max() macro.
i am yet not sure if the used "? :" operator set does qualify as
a left-value. maybe this could be another important reason why
return types here should stay identical to input types.
