Meaning i686-w64-mingw32-gcc uses the Microsoft libraries vs. cygwin
gcc using posix compliant libraries?  Implying LC_MESSAGES not being
defined is yet another instance of Microsoft not following accepted
standards?

The background for my question is https://github.com/htacg/tidy-html5/issues/770
Tidy removed the setlocale call from the library init function, so if
users want a specific locale/language they're going to have to set it
up themselves.
I'd like to update the tidylib example code showing how to set the language, but
  setlocale(LC_ALL, "");
  tidySetLanguage( setlocale(LC_MESSAGES, NULL) );
probably isn't a good example if LC_MESSAGES is missing on some systems.

Thanks
Lee
