| Well, there are other problems reported: licensing and DLL
conflicts.

Regarding the licensing issues, this is no longer an issue with the
MSVC++ Toolkit 2003 but it was with MSVC.NET since distributing a
GPLed program compiled with MSVC.NET requires Microsoft to open up the
source code of some libraries like MSVCRT since this C runtime library
must now be shipped with the binaries (as opposed to earlier versions
of the MSVC++ compiler).

Did you recompile all depending libraries with MSVC++ Toolkit 2003?
