In the following example code:
sa.sa_handler = handler(); /* Address of a signal handler */
we expect to use a function pointer instead of actually calling a function
named handler(). So the parentheses in the above are superfluous.
(Unless there is a function named "handler" returning a pointer to some
_other_ function, of course).
