I need to know whether the setitimer() function is available on all the
OS that Exim supports. I believe it is, and have tested Solaris, SunOS4,
Linux, IRIX, HP-UX, Digital Unix and FreeBSD. However, it would be
reassuring if people who use systems other than the above could compile
and run the short test program that is attached to this message. Just do

[g]cc test.c
./a.out

The output should look like this:

Wait 250 msec
...done
Wait 500 msec
...done
Wait 1000 msec
...done
Wait 1500 msec
...done
Wait 2000 msec
...done
End

and there should be delays of that number of milliseconds each time. In
fact, if the program compiles, I'm sure it will run OK.

Thanks,
Philip
