minor patch for include/fopen-bin.h

["Mark E." <snowball3 at bigfoot dot com>]

That patch adds 't' to the text mode fopen macros for DOS and Windows. Since the 
default can either be binary or text depending on the particular system library, it's 
better to explicitly set text mode instead of presuming it's the default. I'd also like 
to remove the out-of-place swipe at DOS.

include/ChangeLog:

2000-05-30 Mark Elbrecht <snowball3@bigfoot.com>

	* fopen-bin.h (FOPEN_RT, FOPEN_WT, FOPEN_AT): Add 't'.
	  (FOPEN_RUT, FOPEN_WUT, FOPEN_AUT): Add 't'.
	* fopen-bin.h: Revise comment.

  	<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?).
  
     This file is designed for inclusion by host-dependent .h files.  No
