I just tried this re-linking with Janus Ada for Windows. It has three
steps: compile, bind the Ada parts into a .obj file, use Microsoft's
linker to add windows stuff producing a .exe file. A re-bind produced an
identical binary .obj file. A relink produced an .exe that differed in
two bytes, widely separated in the .exe file.
I don't know what might be happening in SunAda, but it clearly doesn't
'occurs with other versions of Ada'.
