These are the lines that fail:

I'm guessing that if you compile the appended program and run it under cron,
it will output "Was ignore", rather than "Was default"

#include <signal.h>
#include <stdio.h>

typedef void (*sighandler_t)(int);

int main () {
    sighandler_t was = signal(SIGPIPE, SIG_DFL);

    if (was == SIG_DFL) {
        puts("Was default");
    } else if (was == SIG_IGN) {
        puts("Was ignore");
    } else {
        puts("Was a real handler");
    }
    return 0;
}
