* include/winnls.h (NLS_FUNCTION, SYSGEOCLASS, SYSGEOTYPE): Add
constants for National Language Support.
* include/winnls.h (NLSVERSIONINFO): Add structure for National
Language Support.
* include/winnls.h (GEO_ENUMPROC): Add callback for National
Language Support.
* include/winnls.h (EnumSystemGeoID, GetCalendarInfo[AW],
GetGeoInfo[AW], GetUserGeoID, SetCalendarInfo[AW], SetUserGeoID):
Add functions.
* include/winnls.h (IsNLSDefinedString, GetNLSVersion): Add
functions. Strange... I am unable to find which library contains
these functions. Can't find anything with pexports. Any clue?

SetUserGeoID): Add functions.
