This is THREE stage linking and if I simply use a two stage process to
build
a relocatable DLL according to
http://www.cygnus.com/misc/gnu-win32/building-reloc-dlls.txt
that DLL can not be loaded via LoadLibrary into a huge application like
JDK Java VM.

So the question is: is this need for the third stage a linker bug or a
necessary feature?
