I'm surprised that that would be a problem, at least for Unix and Windows 
files. It's pretty simple to design Text_IO so that it can read either 
properly; that's how Text_IO in Janus/Ada works. (The only difference for it 
between Windows and Unix versions is the characters output by New_Line). Of 
course, such a Text_IO would make a real hash out of old Mac files. (I 
usually use an Ada program to convert text files to Windows format; it's 
just a simple loop of Get_Line/Put_Line pairs.)

But if you don't want to change the terminators (or your compiler has an 
unnecessarily inflexible Text_IO), I'd suggest using Stream_IO. Of course, 
then you'll have to do your own buffering of input (but that's usually a 
good idea anyway).
