I just re-examined the licensing of the GLIBC locale data and it turns
out that not *all* locale files have a free enough license to be used
by Cygwin.  Some have no licenses at all, some are explicitely under GPL.
Only 166 out of 266 locales are usable without licensing problems.

Other than that, here are the sources to generate the locale data,
as well as the generated files: http://www.vinschen.de/localedata/,
for those who are interested in this stuff.
