2015/02/25
	+ modify gauge widget to keep from erasing a second gauge widget, e.g.,
	  via the "--and-widget" option.  This is a cosmetic change to match
	  behavior of dialog 1.0 (report by Jason Orendorf).
	+ add configure option "--with-man2html"
	+ add configure options for versioned symbols, from ongoing work on
	  ncurses.
	+ update configure macros, e.g., for shared libraries
