While we're talking about signal(), I got the impression that the behavior
of signal handling functions was operating system dependent (e.g. AT&T
UNIX causes the programmer installed signal handler to be replaced by 
the system routine when the signal in question occurs, but BSD UNIX does
not replace the programmer's routine).  I noticed in an article about the
dpANS (am I correct in assuming that this means something like the
draft of the proposed ANSI standard?) the signal function -- how is the
behavior of this specified, is it specified in a portable fashion or do
they leave it up to the operating system?
