do_password

[Dantin]

     Question while compiling I get this error:

act_info.c: 2730: Implicit decleration of the word 'crypt'.

     Now that was annoying so I set about to remidy this situation. Here is
the actual code:

    if (strcmp ((char *) crypt (arg1, ch->pcdata->pwd), ch->pcdata->pwd)) {
        WAIT_STATE (ch, 40);
        send_to_char ("{RWrong password.  Wait 10 seconds.{x\n\r", ch);
        return;
    }

This is found in the do_password function. What would I have to do in order
to stop getting this Implicit Decleration? Thanks before hand.
