Subject: base-3.14.10: libcurses vs. libncurses

Hi all,

I have once again a (stupid/nasty?) question concerning the usage of libcurses vs. libncurses

In configure/os/CONFIG.Common.linuxCommon of base-3.14.10 we see the line:

LDLIBS_READLINE = -lreadline -lcurses

Knowing that I could redefine it with an additional, local, site-specific CONFIG.... file
I still have the basic question why it is still "old" curses library libcurses, given the fact (AFAIK) nowadays (new=n) libncurses is used.
(q.v. Wikipedia: http://en.wikipedia.org/w/index.php?title=Curses_(programming_library)&oldid=242733108 : "While development of ncurses <http://en.wikipedia.org/wiki/Ncurses> and *PDCurses* continues, UNIX <http://en.wikipedia.org/wiki/UNIX> curses development appears to have halted in the mid-1990s when X/Open Curses was defined"


Couldn't this line be changed to libncurses, are there any reasons against it?

(BTW: Typically libcurses is pointing in many systems by a symbolic link to libncurses)

Just for completeness
(I already solved it by changing the above line, or putting a link, or creating an additional CONFIG file):
I am using an unmodified OpenSuse 10.2 installation
and received during make of base, the following error
