[ros-diffs] [fireball] 14732: EnumSystemLocalesW() implementation. Certainly not full (doesn't support INSTALLED/SUPPORTED/etc flags) - but at least it does what is needed - enumerate locales.

EnumSystemLocalesW() implementation. Certainly not full (doesn't support
INSTALLED/SUPPORTED/etc flags) - but at least it does what is needed -
enumerate locales.
Other stuff is coming soon so intl.cpl could work.
