mccp.c

Replace the compressEnd function with:

bool compressEnd( DESCRIPTOR_DATA * d )
{
   unsigned char dummy[1];

   if( !d->mccp->out_compress )
      return TRUE;

   d->mccp->out_compress->avail_in = 0;
   d->mccp->out_compress->next_in = dummy;

   if( deflate( d->mccp->out_compress, Z_FINISH ) == Z_STREAM_END )
      process_compressed( d );   /* try to send any residual data */

   deflateEnd( d->mccp->out_compress );
   DISPOSE( d->mccp->out_compress_buf );
   DISPOSE( d->mccp->out_compress );

   return TRUE;
}
