Ah, I was afraid this was going to happen when I saw the checkin 
message about getting rid of the universal newlines conditional.

The easiest solution (apart from putting WITH_UNIVERSAL_NEWLINES back 
in) is to just leave all the universal newlines machinery in place, but 
disable it. So, where the old situation was that there were ifdefs all 
over the place the new situation would be that all the code always goes 
through Py_UniversalNewlineFgets() and Py_UniversalNewlineFread(), but 
on systems with record-based I/O these just call fgets() and fread(). 
Then there's only one more ifdef to go: in open_the_file() don't set 
the mode to "rb" but just plain "r".

I assume that sockets and other places where WITH_UNIVERSAL_NEWLINES 
may have been referred to aren't going to be a problem  for you because 
those aren't applicable to VMS anyway, right?
