autoconf test for sleep never completes

checking whether sleep is declared... yes
checking for working sleep...

on 1.7.16 the test take 1 second

-----------------------------
#include <errno.h>
#include <unistd.h>
#include <signal.h>
static void
handle_alarm (int sig)
{
   if (sig != SIGALRM)
     _exit (2);
}

int
main ()
{

     /* Failure to compile this test due to missing alarm is okay,
        since all such platforms (mingw) also lack sleep.  */
     unsigned int pentecost = 50 * 24 * 60 * 60; /* 50 days.  */
     unsigned int remaining;
     signal (SIGALRM, handle_alarm);
     alarm (1);
     remaining = sleep (pentecost);
     if (remaining > pentecost)
       return 3;
     if (remaining <= pentecost - 10)
       return 4;
     return 0;

   ;
   return 0;
}

Should be fixed in the upcoming snapshot.

Thanks for the STC.

fixed on 20120725.

Unfortunately I noticed a different issue, not present in 1.7.16.
Running mc the program never rise and the terminal blanks.
If the process is killed the terminal output is a mess.

It seems some issue with tty control.

Marco

Sorta.

mc plays with STOP signals generated when a process is not the
leader of a tty process group.  I'm astounded that I had this
working well enough to satisfy mc in the past but I definitely
broke it now.

It should be fixed in the latest snapshot.

Thanks for the heads up.  There are a lot of signal changes in
1.7.17 snapshots and you found a problem with them.
