Subject: [PATCH 1/5] issue45067 - Fix _curses compilation in CentOS 7. Verify
 the version of ncurses for extended color support feature usage.

The function extended_color_content was introduced in 2017.  The ncurses-devel
package in CentOS 7 had a older version ncurses resulted in compilation error.
For compiling ncurses with extended color support, we verify the version of the
ncurses library.
