- Hack around bug in libtool as it seems to be broken in shell
function func_lalib_unsafe_p() as this does only work if a
file descriptor 0 exists.

- Update to version 1.2-20150225
+ 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
- Changes from 1.2- 20150125
+ suppress highlighting of character which denotes an abbreviation or
shortcut for the OK/Cancel and other buttons for these widgets, which
use abbreviations for the list shown on the screen: buildlist,
checklist/radiobox, menubox, treeview (Debian #775295).
+ add grid up/left and down/right bindings in editbox.c as synonyms for
field prev and next, respectively when handling the OK/Cancel buttons
(Debian #775294).
