    Does anyone how could this error be fixed? Looking at the 
    /usr//include/signal.h look okay to me.

      13 #define SIG_DFL ((void (*)(int))0)      /* Default action */
      14 #define SIG_IGN ((void (*)(int))1)      /* Ignore action */
      15 #define SIG_ERR ((void (*)(int))-1)     /* Error return */
      16 #else
      17 #define SIG_DFL ((void (*)())0)         /* Default action */
      18 #define SIG_IGN ((void (*)())1)         /* Ignore action */
      19 #define SIG_ERR ((void (*)())-1)        /* Error return */
