This was true in CYGWIN_NT-10.0 2.9.0(0.318/5/3) (x86_64) but is no longer true in CYGWIN_NT-10.0 2.11.1(0.329/5/3) (x86_64). (Reported by Assaf Gordon.) Looking at the changes that occurred in the cygwin git between 2.9.0 (on 2017-08-03) and 2.11.1 (on 2018-08-31) it appears to me that the culprit is the commit 41f72ab4d7c404b8ac2a5e1187d79164992e4483 (on 2018-03-09). I would like to CC its author, Thomas Wolff, but he gave an invalid email address <mintty@users.noreply.github.com> in the commit.

Interesting special case, as EOF is not a character. In newlib/libc/ctype, this could be fixed in iswcntrl_l.c as a special condition, or injected as a special case in the categories.t table.

WEOF is a special value. The difference between wint_t and wchar_t is essentially that WEOF fits into wint_t but is not guaranteed to fit in wchar_t.
