Fix potential segfaults at restore related to ctime().
In some games, restore() passes the result of ctime() to mvprintw() or
some other variadic message-formatting function. If ctime() has not
been declared properly, its return type is inferred to be int instead
of char *. This does not cause a warning because the compiler does not
know the correct type of variadic arguments.
On platforms where ints and pointers are not the same size, this can,
probably depending on alignment, result in a segfault that is not easy
to trace.
Including time.h fixes the problem. Some games manually declared
ctime() and avoided the bug. These declarations have also been
replaced with the include.

.TH ROGUE 6 "1 April 1981" .UC 4 .SH NAME rogue \- Exploring The Dungeons of Doom .SH SYNOPSIS .B @PROGRAM@ [ .I save_file ] .SH DESCRIPTION .PP .I Rogue is a computer fantasy game with a new twist. It is crt oriented and the object of the game is to survive the attacks of various monsters and get a lot of gold, rather than the puzzle solving orientation of most computer fantasy games. .PP To get started you really only need to know two commands. The command .B ? will give you a list of the available commands and the command .B / will identify the things you see on the screen. .PP To win the game (as opposed to merely playing to beat other people high scores) you must locate the Amulet of Yendor which is somewhere below the 20th level of the dungeon and get it out. Nobody has achieved this yet and if somebody does, they will probably go down in history as a hero among heros. .PP When the game ends, either by your death, when you quit, or if you (by some miracle) manage to win, .I rogue will give you alist of the top-ten scorers. The scoring is based entirely upon how much gold you get. There is a 10% penalty for getting yourself killed. .PP For more detailed directions, read the document .I "A Guide to the Dungeons of Doom." .SH FILES .DT .B Score file is searched for in these directories: .PP $ROGUEHOME/rogue52.scr .br /var/games/roguelike/rogue52.scr .br /var/lib/roguelike/rogue52.scr .br /var/roguelike/rogue52.scr .br /usr/games/lib/rogue52.scr .br /games/roguelik/rogue52.scr .br rogue52.scr .PP .B Default save file .PP ~/rogue.sav .SH SEE ALSO Michael C. Toy, .I "A guide to the Dungeons of Doom" .SH BUGS .PP Probably infinite. Currently known bugs are: Sometimes you are still hungry even after you eat food and sometimes you get a monster on the screen in reverse video which may or may not cause a core dump.
