Compiling differences?

[Matias Bordese]

I was using the setitimer function (libc 2.2.4) and according to the 
options I compile with (with gcc 2.96), I got different behaviors 
(besides, the binaries differ too):

gcc -o timer -Wall -ansi -pedantic timers.c
(I get the message: "Alarm clock", and the program finishes)

and

gcc -o timer2 timers.c
(I get the expected behavior)
