 > The issue is caused by lxdialog's cflags which are also used to build
 > nconfig; It would detect *ncursesw* and turn on WIDECHAR support --
 > but the Makefile would still link to plain *ncurses* while building
 > nconfig (which was built without WIDECHAR support).

 > This would cause a crash after using *wattrset* on a WINDOW instance.
 > WIDECHAR *wattrset* would try to set the _color member in the WINDOW
 > struct which does not exist in the NON-WIDECHAR ncurses instance. It
 > would end up clobbering data outside the struct (usually _line entries).

 > An upstream patch fixes the issue, so we're applying it to Buildroot's
 > kconfig.
