У меня перестал собираться перл, не может вычислить некоторые константы
для ioctl в сгенерированном сишном коде.

$ cat /tmp/.private/at/bhap6ejYVA.c
#include <stdio.h>
#include <sys/ioctl.h>
int main() {
printf("TCGETS %ld\n", (long)(TCGETS));
printf("TCGETS2 %ld\n", (long)(TCGETS2));
return 0;
}
$ gcc /tmp/.private/at/bhap6ejYVA.c
