Hi Joseph,

Thanks for your very prompt reply.

And now the penny dropped ... Yes, those #includes were not "protected"
with #ifndef _ISOMAC. After moving them in the proper place the
conformance tests pass.

I must admit that I've spent some time on understanding _ISOMAC, but I
did not found much about it in the manual.

Why it is called _ISOMAC? (My first thought was about some MAC specific
