I couldn't let this one go. Take a look at /usr/include/signal.h:

int	(*signal())();

This is a function returning a pointer to a function returning integer.
The casts for SIG_IGN and friends are also interesting:

#define	SIG_DFL		(int (*)())0
#define	SIG_IGN		(int (*)())1
#define	SIG_CATCH	(int (*)())2
#define	SIG_HOLD	(int (*)())3

'Nuf said.
