Well I installed it and only got one warning...

In function 'strncat',
inlined from 'check_alias' at alias.c:158:
/usr/include/bits/string3.h:153: warning: call to __builtin___strncat_chk might overflow destination buffer

      strncat( arg, argument, MAX_INPUT_LENGTH );

Any ideas?

What's the declaration for arg and argument here?

bool check_alias( CHAR_DATA * ch, char *command, char *argument )
{
   char arg[MAX_INPUT_LENGTH];

It's probably complaining because you need space for the zero byte. Try

strncat( arg, argument, MAX_INPUT_LENGTH-1 );
