	+ improve calculation for amount to scroll in programbox when an "Ok"
	  button might obscure part of the data (report by Florent Rougon).
	+ modify program to permit --separate-output to be used with buildlist
	  and treeview widgets (report by Florent Rougon).
	+ add list-height parameter to manpage description of --buildlist
	  (report by Florent Rougon).
	+ minor fixes to dialog.1 manpage; the reported problem was actually
	  fixed in 20120703 (Debian #726233, patch by Bjarni Ingi Gislason).
	+ add a "Hello World" example to dialog.3 manpage (prompted by
	  discussions with Dustin Oprea, Kevin Ingwersen).
	+ correct comparison in dlg_lookup_key() so that using "bindkey" with
	  a "*" wildcard parameter works as documented (report by Stewart
	  Benedict).
	+ updated configure macros, fixes for clang and mingw.
	+ update config.guess, config.sub
