Draft patch.

As both integer arguments and function-pointer arguments are pointers, using a
generic "void *" (BT_VOID) is the simplest. A more cumbersome alternative would
be to split the generated decl in one for
 int signal_func (int *number, void (*handler)(int))
and one for
 int signal_func_int (int *number, int *handler)
