My understanding is that it must be possible to change the LGPL part to to a 
modified one.

In cases where the LGPL code is in a native shared library or in this case 
also in a DLL, it can be replaced by rebuilding that module from source and 
replacing the respective library file.

In cases where the LGPL code is statically linked into an application, the 
rest of the application needs to be available in re-linkable form, e.g. 
object files.
