The errors are in config.log, that's what one is supposed to look at
when there are configure issues.

Yes, that was on purpose, to avoid the -Werror issue. It's expected to
happen because /usr/include/curses.h doesn't seem to have the wide
support. But -I/usr/include/ncursesw/curses.h is supposed to have. But:

That's what the real issue is in your case.  I now see why, could you
try the attached patch instead?
