A few system call numbers on x86 Linux are defined in terms of a previous definition, e.g., #define __NR_timer_create 259 #define __NR_timer_settime (__NR_timer_create+1) ... #define __NR_mq_open 277 #define __NR_mq_unlink (__NR_mq_open+1) This change assumes the numbers are sorted sequentially in the input file.
