catenate the ff fe prefix in UTF-16 encoded octstr and swapping bytes in words (if it tnecessary)

Hi developers!

I use kannel as SMSGW on the SPARC (with SunOS) platform and I was oblige to implement the following futures in some functions :))

in gwlib/octstr.c 

void octstr_swap_bytes(Octstr *ostr)
{
 unsigned char ch = 0;
 long pos;
 
 seems_valid(ostr);
 
 for(pos = 0;pos < ostr->len - 1;pos += 2)
 {
  ch = ostr->data[pos];
  ostr->data[pos] = ostr->data[pos + 1];
  ostr->data[pos + 1] = ch;
 }
}

in gwlib/octstr.h

void octstr_swap_bytes(Octstr *ostr);

in gw/smsc/smsc_smpp.c (in msg_to_pdu function)

.... 
   /*
     * only re-encoding if using default smsc charset that is defined via
     * alt-charset in smsc group and if MT is not binary
     */

...
    if (msg->sms.coding == DC_UCS2) {
        /*
         * remove the first two bytes FE FF from octetstring (add from yuryx for SMSCv3.2)
         * 
         */
         Octstr *octstr_tmp = NULL;
         short UTF_16_PREFIX = 0xfeff;
         
         #if (defined (__sparc__) || defined (__sparc) || defined (__sun)) 
              octstr_swap_bytes(pdu->u.submit_sm.short_message);
         #endif

         octstr_tmp = octstr_create("");
         octstr_append_data(octstr_tmp, (char*) &UTF_16_PREFIX, 2);
         if(octstr_ncompare(pdu->u.submit_sm.short_message, octstr_tmp, 2) == 0) {
            octstr_delete(pdu->u.submit_sm.short_message, 0, 2);
         }
         octstr_destroy(octstr_tmp);
    }

    /* prepend udh if present */
...


What are mean about the add that code in next CVS commit?
