These changes correspond these entries in ChangeLog:

2011-03-20  Bastian Maerkisch  <bma...@we...>

	* src/win/wgnuplib.c|h, src/win/wgraph.c, src/win/winmain.c, 
	src/win/wmenu.c, src/win/wpause.c, src/win/wtext.c: FAR pointers are
	no longer required.

	* src/win/winmain.c (WinExit): Explicitly close help window on exit.
	Fixes hangs of gnuplot when it is closed via the Windows taskbar 
	and help window	and graph window open.

The later might be the reason for hangs or crashes on exit - but not after
issuing a command. I also don't see why the changes should influence 
opening files. Going over the diff and the source again, I see no obvious 
suspect. 

Removing FAR should be innocent - it should be define'd empty anyway.
(And so is "far" in syscfg.h btw).

One thing which could be different between "cvs checkout" and downloading
via "viewcvs" are line endings. We should check that none of my commits
mixed Unix (LF) and Windows (CR/LF) line endings.
