Probably what I should do could be bisecting the recent commits.
That'd be best, if you can. Thanks.
I did it and found the revision that causes this problem on at
least Cygwin-64. That is d5bb053.
That's strange: that changeset changed just the docs, and the only
changes in code are in xwidget.c (which your build shouldn't compile)
and in keyboard.c, where the changes just remove redundant braces, and
again mostly in places that are built only when xwidgets are
supported.
