Thanks for that it looks easier than MS description of building shareable
objects and def files. Only one small problem i'm having now is that
all_callext_examples fails as it was unable to find some files. I assume its
some problem so obvious its hitting me in the face, just cant see it.

Anyone any ideas ?

thanks
