Many thanks Corinna. If I understand you correctly, "talk like the Romans" means
"just make everything pure POSIX calls", right?  

Secondly, if that's the case, what would the purpose of the Windows defines be?
(Apart from confusing simple folks like me :)  Put another way, if I want to use
those defines (i.e. flee Rome and settle in Babylon), what version of ioctl
should I call and what libs should I link in?  

Thirdly, and I'm probably pushing it now, if you have some favorite references
to read on the above dichotomy? I'd appreciate the pointer. Or is it *pointer?
