>Summary: socketmodule.c: inet_pton() expects 4-byte packed_addr

Initial Comment:
In the Modules/socketmodule.c file, the inet_pton function 
implicitly treats "long packed_addr" as a 4-byte object or 
expects that the required 4-bytes is at 
&packed_addr[0]-[3]. This is not true under 
SUPER-UX/SX. In order to get this working right, I 
changed the data type from "long" to "int". This now 
works properly. 
 
-----Modules/socketmodule.c: #3825  
 /* 042303; JM; this routine really expects a 4-byte  
packed_addr  
 * not a long; long on SX is 8-bytes! */  
#if SX  
        int packed_addr;  
#else  
        long packed_addr;  
#endif 
... 
         if (packed_addr == INADDR_NONE) 
            return 0; 
        memcpy(dst, &packed_addr, 4);
