I used 

g++ -Wall -I. -shared -g -c dll.cpp -o dll.o
g++ -Wall -shared -o libdll.dll dll.o
g++ -Wall -I. -g -c dlltest.cpp -o dlltest.o
g++ -Wall -o dlltest dlltest.o -L. -ldll -Wl,--enable-auto-image-base

I still have the stackdump problem.

I used hd to look at the files I created with emacs and there are no
strange characters.
