It returns the LOGNAME, used to find /usr/mail/LOGNAME mail storage file.
You might be able to derive it from a getenv of LOGNAME or ...

I also changed the line
	signal(SIGINT,clear&exit) to trap to a null function on SIGINT
so that the clock wouldn't go away when I interrupted a program.
I'm running SysV 3.0, and I don't get the 'mail' prompt, just the clock.
I went to sdb, which is kind of hard(?) on a program that is in background.

Thanks Joel.  I don't even care about the mail stuff, the clock is great.
