My understanding is that there are CYGWIN and MINGW prereqs that are mutually exclusive (if you are on MINGW you cannot be on CYGWIN and vice versa), and WINDOWS is a short-hand for "we are either on MINGW or CYGWIN", and I am not sure if it clarifies anything to rewrite "we do not want to be on MINGW to run these tests" to "anything non Windows is fine, by the way, CYGWIN is also OK". If we are planning to add another variant that falls into umbrella WINDOWS that is not CYGWIN, and that new variant falls short of the requirement of the tests in this script just like MINGW does, then the suggested rewrite does make quite a lot of sense. There would be not just two but more variants in Windows family, and if Cygwin is the odd man out, then the rewritten one would convey that more clearly. But with only two, as long as everybody understands what MINGW is, I think "this part does not work on MINGW" is more concise and clear. As Đoàn Trần Công Danh pointed out, the TODO: comment may need to be updated. For future-proofing, perhaps "a more similar) error on all platforms." would be appropriate. Thanks.
