Hi, Sean.

As you can see tests are failing on win2000 and winxp because these 
calls are not available on these platforms. You should use 
GetProcAddress() to fix that.

First argument should be 'wstr' as well.

Same.

Please use cleaner argument names, like 'localename', 'flags', 'date', 
'format', etc. So lowercase, no prefix.

No real need for temporary 'lcid' variable.
