This synopsis is :

/-----------------
| #include <signal.h>
| 
|      void
|      (*signal(int sig, void (*func)(int));)()
\-----------------

(note the semi-colon...)

I think it would be better to read :


/-----------------
| #include <signal.h>
| 
|      void
|      (*signal(int sig, void (*func)(int)))(int);
\-----------------

Also, the FreeBSD's typedef'd synopsys is somewhat clearer:

/-----------------
| typedef void (*sig_t)(int);
| 
| sig_t
| signal(int sig, sig_t func);
\-----------------

it could be nice to add it in the synopsis as an alternative for the
basic syntax.
