On UN*X, always use sigaction(), and always have signal handlers return void.
Some time between the mid 1980's and 1990 called; they want their
old-fashioned UNIX signal handling back. ANSI C has had signal handlers
returning void sincer, well, 1989, and POSIX has had sigaction() since
close to forever. No need to worry about really old UN*Xes here.
On Windows, it's also void (as per ANSI C); use signal().
