+Subject: [PATCH] Check for termcap support in split tinfo libs
+
+Previously only the main ncurses libs were checked leading to users with
+enabled unicode support (ncursesw) and split tinfo libs running into
+segfaults since the checks would fallback to setting TERMCAP_LIB=-lcurses.
+
+Fixes #568.
