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

21 Nov 2004

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
