           Version: 5.4p1
          Platform: Sparc

Overview: 

   The function derelativise_path() in servconf.c calls getcwd(NULL,0) 
and using zero for the size argument is unsupported on Solaris.


Steps to Reproduce: 

    1) uncomment #AuthorizedKeysFile     %h/.ssh/authorized_keys
       from /etc/ssh/sshd_config

    2) restart sshd


Actual Results: 

   sshd failed to start with the following message
   derelativise_path: getcwd: Invalid argument


Expected Results: 

   sshd starts with no error messages
