Stuck with the error below

i'm also unable to compile

although i'm not getting the depracated errors.

Also, on Arch AUR:

./compile sig_pause.c

DESCRIPTION
       Don't use this function.  Use sigsuspend(2) instead.

I deleted ifdef in sig_pause.c:

#include <signal.h>
#include "sig.h"
#include "hassgprm.h"

void sig_pause(void)
{
  sigset_t ss;
  sigemptyset(&ss);
  sigsuspend(&ss);
}

@jodreyer's fix on the conf-cc file seems to also work and less invasive:

- gcc -O2 -Wall -Wshadow -Wcast-align -Wwrite-strings
+ gcc -O2 -Wall -Wshadow -Wcast-align -Wwrite-strings -D_GNU_SOURCE
