Hi

We have always ignored this small rounding differences, but here the "end
effect" was that the generated document was different, as "hyphenation", word
splitting worked differently.

My little surprise was, that we have changed the C++ compiler option, to use the
"standard" IEEE, but the result was still not the same in Windows as in zOS
