LOL ... What an odourful way of (out)putting it. This reminds me of a selenium rectifier that has a horrible smell when fried - more suitable name for it would be "selenium rectumfier".

You have that completely right. Trying to code fully independent code that is usabe AS SUCH everywhere is doomed to fail and when miraculously passed compilation it is VERY hard to test. Any modification to the code should be tested in all target platforms. I understand this and have gone through the PITA of it as I was stubborn enough to stumble on the lying log that was clearly marked by someone more wiser than me.

It is very good practise to make portability questionable. This way it comes clear that it is not at all clear when to make such code and when not.



Well, isn't communication wonderful. I have noticed that we agree 99 percent of the issues we have been discussing but still we seem to tangle on the few differences there are. Most welcome discussion after all these years. I attach a sample header file whic has served my coding unaltered for 15 years now. I believe You will find it quite familiar.
