bug#35342: configure.ac: scan also libtinfow for tputs()

[Дилян Палаузов]

Hello,

on my system I have no libtinfo, libncruses, libcurses, libterminfo and libtermcap.

But I have libtinfow and libncursesw, and the former contains tputs.

• Tweak ./configure.ac to scan also libtinfow and libncursesw for tputs() before giving up.

With emacs 26.2 this is not the case.

Regards
  Дилян

Yes, when you reported it previously (Bug#33977), it was only fixed on
the master branch (what will become Emacs 27.1).  Should we backport [1:
a3d52b3057] to emacs-26 (so it will be fixed in Emacs 26.3)?

OK, I guess, although I don't really understand whether tputs in
ncursesw is a drop-in replacement for its namesake in ncurses: we
don't use wide characters with the curses APIs, AFAIK.

Hello,

I altered my ./configure to check tinfow/ncursesw, it uses tputs from tinfow and I have not experienced any problems.

I have forgotten, that I have reported that previously.

I understand, but the general question still stands.

Pushed to emacs-26.  No clue about the ncursesw vs ncurses though.
