This one looks pretty good to me, but I have one error and a few nits
to correct:

The error:
+  {
+    ERR("GetLocaleInfo of 0x%x failed in 2nd stage?!\n", localeValue);
+    SysFreeString(*pbstrOut);

You should set *pbstrOut to NULL in this case.

The nits:
You have a couple small errors in the comments:
- You misspell iWeekday
- The comment for iWeekday in the params section implies 0 is allowed,
but the first check in the function disallows it.

You also inconsistently put spaces after commas - please do in all cases.

Attaching a test with the patch would certainly help.
