Thanks for your reply, and I also thought of your suggestion to wrap the _exit. The fact is that dejagnu does
the wrapper to both exit() and _exit(), but it give a higher priority to the exit(), which means if you both
call exit() and _exit(), it will only output the return value in exit(). Someone told me that you shouldn't
explicitly call _exit() inside an exit(), and that's why the dejagnu skip the second _exit() output. However,
I'm not sure about this, as there're quite a few c++ test cases are doing the same thing.

Ok, I will commit with this version.
