KERNEL32: add a test case for CompareStringW undocumented flag 0x10000000

[Mike McCormack]

Hi All,

I've written a regression test that shows what the undocumented flag 
0x10000000 passed by shlwapi.StrIsIntlEqualW/A to CompareStringW/A does. 
  I discovered the different by writing a short program that compared 
the output of CompareString with and without the flag for all unicode 
characters... it took a while to run :)

The flag (0x10000000) passed to CompareString reverse the sort order of 
a number of unicode characters.  I've got no idea why it would want to 
do that... maybe somebody can shed some light on what the reason behind 
this would be?

Mike


ChangeLog:
* add a test case for CompareStringW undocumented flag 0x10000000
