It got corrected shortly afterwards. The non-typo version is:
#define DERROR(dbg, fmt, args...) \ do { if(DEBUG_##dbg) \ printk(KERN_INFO "irnet: %s(): " fmt, __FUNCTION__, ##args); \ } while(0)
Example: #define DEBUG(fmt, args...) \ printf("%s(): " fmt, __FUNCTION__, ## args)
int main(void) { DEBUG("I am hungry.\n");
exit(0); }
# gcc -Wall -Os -o moehre -s moehre.c # ./moehre main(): I am hungry. #
Thunder -- assert(typeof((fool)->next) == typeof(fool)); /* wrong */
