[ECOS] ZLIB and gzip - Bug in fread()

[Stephen Polkowski]

Jesper,

	The first bug that I've found is in the fread() library call.  fread 
isn't updating it's buffer pointer for multiple reads. Notice that the 
read is done with ptr, but only ptrc is incremented.  The call should be 
made with ptrc. When I make the change, gzip starts working.

	Should I submit a patch?  What is the process of submitting patches. 
Thanks.

Regards,

Steve

     while (!err && bytes_to_read) { // if no err, but not finished
         err = real_stream->refill_read_buffer();
         if ( !err ) {
             err = real_stream->read( (cyg_uint8 *)ptr, bytes_to_read,
                                      &bytes_read );
             bytes_to_read -= bytes_read;
             total_read += bytes_read;
             ptrc += bytes_read;
         } // if
     } // while
