Browse Source 
Some warnings were mentioned

Add a prototype ahead of the function
Use a non-const copy of SERVER_ADMIN_MSG

quick-tested by:
- uncommenting the following in include/unixconf.h
  /* #define SERVER_ADMIN_MSG "adminmsg" */
- building NetHack
- creating a test message:
  echo "server_admin: system is going down at 2 pm" >~/nh/install/games/lib/nethackdir/adminmsg
- playtested and received the desired message
