/* Macros for the 'type' part of an fopen, freopen or fdopen. 

	<Read|Write>[Update]<Binary file|text file>

   This version is for "binary" systems, where text and binary files are
   different.  An example is Mess-Dose.  Many Unix systems could also
   cope with a "b" in the string, indicating binary files, but some reject this
   (and thereby don't conform to ANSI C, but what else is new?).
