Checked in, with some changes:

	1) I removed the debugging messages;

	2) I left the file type checks in - they should be done even when 
reading the standard input;

	3) on Windows, it sets the standard input to binary mode;

	4) random mode won't work without a file name - it needs two completely 
independent file descriptors, with separate file offsets, but  the only 
thing you can do with the standard input is to dup it, but "dup()" gives 
you a descriptor that shares a file offset with the original descriptor 
- so it checks for that and returns an error if you try to open "-" for 
random access.  (Maybe on some UN*Xes you could do it with "/dev/stdin", 
if opening "/dev/stdin" behaves like an open rather than a dup, so that 
the new descriptor has a different file offset.)
