So this isn't really a bug. It's more an update for compliance with the newest incarnation of gcc. So here goes.

imc.c:

char *imc_mudof( const char *src )
{
   static char mud[SMST];
   char *person;

   if( !( person = strchr( src, '@' ) ) )
      imcstrlcpy( mud, src, SMST );
   else
      imcstrlcpy( mud, person + 1, SMST );
   return mud;
}

Becomes:

char *imc_mudof( const char *src )
{
   static char mud[SMST];
   const char *person;

   if( !( person = strchr( src, '@' ) ) )
      imcstrlcpy( mud, src, SMST );
   else
      imcstrlcpy( mud, person + 1, SMST );
   return mud;
}

imc.c, imc_send_social

   CHAR_DATA *skeleton = NULL;
   char *ps;
   char socbuf[LGST], msg[LGST];

Becomes:

   CHAR_DATA *skeleton = NULL;
   const char *ps;
   char socbuf[LGST], msg[LGST], tmp[SMST];

And further down,

         ps[0] = '\0'; 
         imcstrlcpy( mud, ps + 1, SMST );

Becomes:

         imcstrlcpy( tmp, ps, SMST );
         snprintf( mud, SMST, "%s", tmp );

act_comm.c, do_group

CHAR_DATA *victim = NULL;

Becomes:

CHAR_DATA *victim = NULL;

Color.c, send_to_desc_color

   char *colstr;

Becomes:

   const char *colstr;

Color.c, send_to_char_color

   char *colstr;

Becomes:

   const char *colstr;

Color.c, send_to_pager_color

   char *colstr;

Becomes:

   const char *colstr;

misc.c, pullorpush

Becomes:

misc.c, do_takedrug

int sn;

Becomes:

int sn = 0;

mud_comm.c, get_color

   char *cptr;

Becomes:

   const char *cptr;

Ships.c, do_makeprototypeship

int count;

Becomes:

int count = 0;

Shops.c, get_cost

int cost;

Becomes

int cost = 0;

Swskills.c, do_bribe

int percent, amount;

Becomes:

int percent = 0, amount;

Update.c, aggr_update

      for( ch = wch->in_room->first_person; ch; ch = ch_next )
      {
         int count;

         ch_next = ch->next_in_room;

Becomes:

      for( ch = wch->in_room->first_person; ch; ch = ch_next )
      {
         int count = 0;

         ch_next = ch->next_in_room;
