[cvsnt] Client connection failing to cvsnt on a HP-UX UNIX box using pserver - HPUX patch fix

[Haitham Hamad]

Tony,
 
I applied your patch for src/library_unix.c and cvs is working ok with
the .la files. 
 
On another note, I remembered when I compiled the source for the first
time, I had to make a change to lockservice/server.cpp file. The make
was complaining about "socklen_t addrlen;"
 
#ifdef _WIN32
                int addrlen;
#else
                socklen_t addrlen;
#endif
              
 
 
TO
#ifdef _WIN32
                int addrlen;
#else
                int addrlen;
#endif
    

which obsoletes the purpose of the if statement, but that what worked
with my box. 
 
thanks
Haitham
