sorry I did read what you said in the last mail too quickly: I now understand what you are 
talking about. I always build in static Unicode Debug mode thus I don't have the DLL 
problem but I do see various warnings when I set to 4 the warning level.
This lead me to find some problems.

In particular

   wxFileOutputStream outfile(fileName);
   outfile.Write(wxMemoryInputStream(m_buffer));

must be changed:

   wxFileOutputStream outfile(fileName);
   wxMemoryInputStream tmp(m_buffer)
   outfile.Write(tmp);

since mingw32, GCC and all other ANSI-compliant compilers won't accept this. I attach as 
example the error log from mingw. Otherwise the code compiles with MSVC only.
Also code like

    for (int i=.... ) {
    }

    printf("%d", i);

must be turned into:

    int i;
    for (i=.... ) {
    }

    printf("%d", i);

since for ANSI C++ the "i" died inside the FOR loop (but not for MSVC).

The two errors above are the price to pay when you use a compiler like MSVC ;-)
