Thank you for your answer. A little community of people writing for the same nearly unknown language two different standard libraries that share lot of functionality. I don't remember other uncommon (or even common) languages in this situation :-) Even if I can accept that there is no solution, I will never see this as something normal or sane :-) Bye, bearophile
